The department chair was staring at him.

Later someone told him he'd been giggling.

KATIE had come into a small inheritance. She celebrated by taking him to dinner and a movie. "What did you want to see?" he asked her. had come into a small inheritance. She celebrated by taking him to dinner and a movie. "What did you want to see?" he asked her.

Thurgood. The film was, of course, a biopic of Thurgood Marshall. "Is that okay with you?" The film was, of course, a biopic of Thurgood Marshall. "Is that okay with you?"

Not really. But he didn't conceal his lack of interest very effectively. "Sure," he said.

"What's wrong? It's gotten good reviews."

"Nothing's wrong. Let's go see it."

"Dave . . . ?"

"No. It's fine." Dave had developed a resistance to any kind of drama written around racial conflict. He'd never been able to bring himself to read To Kill a Mockingbird To Kill a Mockingbird. Or to see A Raisin in the Sun A Raisin in the Sun. His folks had given him a copy of The Souls of Black Folk The Souls of Black Folk, which included some of DuBois's essays and letters. It was painful reading, and Dave didn't like pain. He refused to watch movies about terminal illness or marital breakups. He wanted his entertainment light light. Entertainment, he insisted, should entertain entertain. Life can be hard enough.

"What do you you want to see?" want to see?"

There was a baseball romance, Rounding Third Rounding Third, that he'd have liked. "No. Let's go see Thurgood Thurgood. That's fine."

"You're sure?"

"Absolutely."

FOR Shel, discretion was even more difficult. Helen had swept him off his feet. On that first date, the same day he'd taken Dave to 1931, they'd gone to dinner at Fayette's, his favorite luxury nightspot. There they ate by candlelight, while a pianist played "It Had to Be You." They talked about trivia. She was commenting on how enticing the atmosphere was, and he said something about work or maybe about a movie he'd seen recently. Like Dave, he was aching to talk about how he'd been walking the streets of Depression-era New York, that he could take her there Shel, discretion was even more difficult.

You want the date of a lifetime, sweetheart? You want the date of a lifetime, sweetheart?

"So what exactly do do you do, Shel?" she asked. And managed to look interested. you do, Shel?" she asked. And managed to look interested.

What did he do? "I do public relations for Carbolite. Basically, we sell engineering systems. To individuals or to manufacturers. Anybody who wants to build a better house, we can show him how."

Yawn.

"Really?" she said. "How does that work?"

Well, the truth is, love, I travel in time. The other night I rescued Winston Churchill. Tomorrow, I'm going to pop by and say h.e.l.lo to Cicero. He explained about making presentations to engineers and how people had better washing machines because of Carbolite technology. It took only a few minutes before her eyes began to glaze.

"But enough about me," he said. "How's life in medicine these days?"

She was too smart to take the bait. She asked whether he really enjoyed the theater or actually used the Disciples as a way of meeting women. What did he do when he wasn't selling better washing machines? (She didn't phrase it that way, but he understood what she meant.) Where did he want to be ten years down the road?

That one stopped him cold. Where indeed? He had no ambitions, really, beyond the moment. A decade from now, he'd like to be making a substantial amount of money. And he'd like to be happily married, maybe with one or two kids. But suddenly that all sounded mundane. And it occurred to him he could take his time device and go look. Find out what he'd be doing. Find out what they'd both both be doing. be doing.

And he wondered, while he talked in a circle about ambitions he really didn't have, how it would affect them if he did did take her forward so they could find out. take her forward so they could find out.

Let's go look.

"I'd like to be with a larger corporation," he said, finally. "One of the blue chips, maybe GE, running their their PR office." PR office."

"Well." She sipped her rum and c.o.ke and looked at him across the rim of her gla.s.s with those spectacular blue-green eyes. "Good luck with it, Shel." She almost sounded as if it all had some significance.

There was a time when he had seriously believed in the transformative power of public relations. Image is everything. If you believe it's a better world, it is is a better world. But somehow selling a more efficient computer system to the a better world. But somehow selling a more efficient computer system to the Wall Street Journal Wall Street Journal no longer galvanized his sense of worth. The existence he had imagined for himself, creative, appreciated, a guy who walked into the room and everybody automatically got quiet-it had happened. But he couldn't see that it mattered. no longer galvanized his sense of worth.

He wondered if Helen would be interested in talking baseball.

GALILEO had been born in February 1564, in Pisa. It was a time when Aristotelian astronomy was held in high regard, when the a.s.sumption that the sun and planets rotated around the Earth was dogma, and when any who disagreed risked more than their reputations.

"He first heard about the telescope in 1609," said Shel.

"When did he die?" asked Dave.

"In 1642."

"So, if we a.s.sume that he would want the meeting to take place after Galileo started using the telescope-"

"We can't a.s.sume that."

"We can't?"

"There's a good chance he'd have wanted to see the Pisa experiment."

"Dropping cannonb.a.l.l.s off the Tower?"

"Yes."

"When did that happen?"

"Sometime between 1589 and 1592."

"That leaves us half a century to search."

"Actually, it's possible the Pisa thing didn't happen at all. Some people think the experiment is just a legend."

"All right." They were in the den at Shel's town house. "I guess our more immediate problem is the language. "Parla italiano?" "Parla italiano?"

Shel smiled. "Devo andare adesso." "Devo andare adesso."

"You said, 'I have to go now.' "

"It's a joke. Parlo italiano Parlo italiano like a bandit." like a bandit."

"I see we're in for a long trip."

"I'm not especially competent, Dave. But I've been working at it. We went to Rome a couple of times, and once to Venice. I was in high school then, but I picked up some of the language, so I wasn't really starting from nothing."

"So now you want to practice?"

"If you have the patience."

"I'm at your disposal, Shel."

"Okay. No more English for the rest of the night."

IF there was anyone David could have confided in, it was Katie Gibson. Katie was a lifeguard at the local YWCA. They hadn't exactly been doing a lot of dating, but he and Katie were friends. Both were waiting for the One and Only to show up. Meanwhile, they were marking time with each other. Had even slept together a couple of times. But the chemistry wasn't really there. Dave had even let Katie know about his interest in Helen, whom she'd never met. She was horrified when he told her about introducing Helen to Shel. She'd wished him luck and advised him to be more aggressive. "Get out front with her," she'd said. "Hire a bra.s.s band to follow her around if you have to." there was anyone David could have confided in, it was Katie Gibson. Katie was a lifeguard at the local YWCA.

"That would put her off," Dave had said.

"Not if there's anything there. If she likes you, you need to take some action. Sweep her off her feet. If she's really not interested, nothing you can do will change that."

"You're saying I've nothing to lose."

"Exactly."

Still, he hadn't hired the bra.s.s band, though they'd have been a magnificent sight, standing outside her office down at the medical plaza.

Nor, of course, did he tell Katie about the time travel. As he had elsewhere, he came close. He was on the phone with her, and they were talking about upcoming movies, when she commented that the Churchill biopic, Her Finest Hour Her Finest Hour, would be opening in a couple of weeks. She was anxious to see it. One of the things he especially liked about her was that she was not much inclined toward chick flicks. Katie enjoyed conflict. Especially the ones featuring an ordinary guy, or woman, who simply decides he's had enough and takes on whatever const.i.tutes the evil empire, the local mob, corrupt politicians, or maybe just the bully across the street. "It looks like fun," "It looks like fun," she said. she said.

And he imagined himself telling her: Katie, I've talked to Churchill. In 1931. Really. Katie, I've talked to Churchill. In 1931. Really.

"You're laughing," she said. she said. "If you don't want to-" "If you don't want to-"

So then I said to Winston- "No, no," he interrupted. "That's good. Let's do it." "No, no," he interrupted. "That's good. Let's do it."

"What was so funny?"

"Umm. No, I was thinking about something else." A new Superman film was opening. Dave had never thought about it before, but it must have been hideously diffic ult for Clark Kent to keep his secret. Especially in the face of Lois's superior att.i.tude.

DAVE sent Shel some Italian films, with the suggestion he watch each of them until he could actually follow the dialogue. Meanwhile, he refreshed his own skills by reading editions of seventeenth-century Italian cla.s.sics in the original. He settled in each evening with Machiavelli and the poet Giambattista Marino.

Meanwhile, he refreshed his own skills by reading editions of seventeenth-century Italian cla.s.sics in the original. He settled in each evening with Machiavelli and the poet Giambattista Marino. He read La Reina de Scotia La Reina de Scotia, a drama about the trial of Mary, Queen of Scots, by Federico della Valle. He struggled through Dante, and for the first time read the entire work, and not simply The Inferno The Inferno. When he was finished, he understood why people still read The Inferno The Inferno and ignored the other two books. He suggested that they watch some operas together. "I've no taste for opera," Shel said. But they downloaded and ignored the other two books. He suggested that they watch some operas together. "I've no taste for opera," Shel said. But they downloaded L'Orfeo L'Orfeo, Pagliacci Pagliacci, and Lucrezia Borgia Lucrezia Borgia, and, for opening night, Don Giovanni Don Giovanni. They got some pizza in, invited Helen and Katie, and turned it into a party. But Shel and Katie both suffered visibly through the opera, and it did nothing for Shel's Italian.

Two nights later, they did Pagliacci Pagliacci, this time without the women. Shel spent much of the evening glaring at the screen. "Give it a chance," said Dave. "Relax and enjoy the show."

Shel tried. "But," he complained, "I never know what's going on."

"That's the whole point of the exercise. Your Italian's a bit weak."

"They could be singing in English, and I don't think I could follow it. There's got to be an easier way." He held up one of the software packages his father had been using: Speak Italian Like a Native.

"Good," said Dave. "How about the movies I sent over? Have you watched any of those?"

"Amici Miei."

"Okay. And . . . ?"

"Il Ciclone."

"Good comedies."

Shel looked doubtful. "Absolutely."

"Can you understand them?"

"Some."

"Okay. Hang in."

WHEN, several weeks later, Shel had finally gotten a handle on the language, they decided it was time to go find his father. "First, though," he said, "we'll need a wardrobe. And it probably wouldn't be a bad idea to grow a beard." He'd already started one. several weeks later, Shel had finally gotten a handle on the language, they decided it was time to go find his father. "First, though," he said, "we'll need a wardrobe. And it probably wouldn't be a bad idea to grow a beard." He'd already started one.

"You're kidding."

He frowned at Dave's jaw. "I think you'll look out of place like that."

They drove into Center City and visited Emilio's Costume and Wardrobe Shop on Walnut Street. The walls were covered with photos of people dressed as sheiks, Roman soldiers, princesses, and Zorro. Some high-school kids, with a teacher, were wandering among the racks, apparently selecting costumes for a play.

Dave was measured for two doublets, both with a calico design. He also got a soft blue huke, which was a kind of cloak, lined in white squirrel fur. When he tried it on, it hung to his thighs. "We'll have to take this one in a bit," said the clerk. "And let this one out." He made notes, then put the garments aside.

Hats were next. They tried several types but wound up with pillboxes. "What is it for?" asked the clerk. "A festival? Or are you in a show?" He was middle-aged, sporting a brown beard with streaks of gray, with gray eyes, full cheeks, and an att.i.tude that Dave could think of only as theatrical pretense. This was a guy who, if he weren't working at Emilio's, wanted you to think he'd be directing on Broadway.

"It's a show," said Shel.

"Which show?"

Shel glanced toward Dave.

Dave smiled. "Two Gentlemen of Verona."

"That's interesting," said the clerk. "I don't think we've ever had anyone do that locally." He adjusted the pillbox on Dave's head, looked satisfied, and announced it was perfect. "Which theater are you gentlemen with?"

"Delaware Township," said Shel.

The clerk let them see he'd never heard of them, but he said nothing.

Eventually they came to the footwear. Dave found a pair of soft round-toed green sandals that he liked. "These should complete the costume nicely," said the clerk, handing him a pair of stockings almost as long as his legs. They were also green, but of a darker shade. And they were complete with leather soles. Dave went back into a dressing room, got out of his slacks, pulled the socks on, and slipped his feet into the shoes. They were surprisingly comfortable. He came back out and submitted to inspections by both the clerk and Shel. The clerk p.r.o.nounced himself pleased, and Shel said he looked the very picture of a Renaissance scholar.

When they'd finished, Shel insisted on paying. The clerk promised to have everything ready within two days, and arrangements were made to ship overnight.

They came out onto Walnut Street and turned west toward the parking lot. "Time travel," said Dave, "isn't the way I would have expected it to be."
