"Waiter, the check, please," ordered Kennedy leisurely.

When he received it, he seemed to be in no great hurry to pay it, but went over one item after another, then added up the footing again.

"Strange how some of these waiters grow rich?" Craig remarked finally with a gay smile.

The idea of waiters and money quickly brought some petty reminiscences to her mind. While she was still talking, Craig casually pulled a pencil out of his pocket and scribbled some figures on the back of the waiter's check.

From where I was sitting beside him, I could see that he had written some figures similar to the following:

5183 47395 654726 2964375 47293815 924738651 2146073859

"Here's a stunt," he remarked, breaking into the conversation at a convenient point. "Can you repeat these numbers after me?"

Without waiting for her to make excuse, he said quickly "5183." "5183,"

she repeated mechanically.

"47395," came in rapid succession, to which she replied, perhaps a little slower than before,

"47395."

"Now, 654726," he said.

"654726," she repeated, I thought with some hesitation.

"Again, 2964375," he shot out.

"269," she hesitated, "73--" she stopped.

It was evident that she had reached the limit.

Kennedy smiled, paid the check and we parted at the door.

"What was all that rigmarole?" I inquired as the white figure disappeared down the street.

"Part of the Binet test, seeing how many digits one can remember. An adult ought to remember from eight to ten, in any order. But she has the mentality of a child. That is the queer thing about her.

Chronologically she may be eighteen years or so old. Mentally she is scarcely more than eight. Mrs. Sutphen was right. They have made a fiend out of a mere child--a defective who never had a chance against them."

CHAPTER XXVII

THE LIE DETECTOR

As the horror of it all dawned on me, I hated Armstrong worse than ever, hated Whitecap, hated the man higher up, whoever he might be, who was enriching himself out of the defective, as well as the weakling, and the vicious--all three typified by s...o...b..rd, Armstrong and Whitecap.

Having no other place to go, pending further developments of the publicity we had given the drug war in the Star, Kennedy and I decided on a walk home in the bracing night air.

We had scarcely entered the apartment when the hall boy called to us frantically: "Some one's been trying to get you all over town, Professor Kennedy. Here's the message. I wrote it down. An attempt has been made to poison Mrs. Sutphen. They said at the other end of the line that you'd know."

We faced each other aghast.

"My G.o.d!" exclaimed Kennedy. "Has that been the effect of our story, Walter? Instead of smoking out anyone--we've almost killed some one."

As fast as a cab could whisk us around to Mrs. Sutphen's we hurried.

"I warned her that if she mixed up in any such fight as this she might expect almost anything," remarked Mr. Sutphen nervously, as he met us in the reception room. "She's all right, now, I guess, but if it hadn't been for the prompt work of the ambulance surgeon I sent for, Dr.

Coleman says she would have died in fifteen minutes."

"How did it happen?" asked Craig.

"Why, she usually drinks a gla.s.s of vichy and milk before retiring,"

replied Mr. Sutphen. "We don't know yet whether it was the vichy or the milk that was poisoned, but Dr. Coleman thinks it was chloral in one or the other, and so did the ambulance surgeon. I tell you I was scared. I tried to get Coleman, but he was out on a case, and I happened to think of the hospitals as probably the quickest. Dr. Coleman came in just as the young surgeon was bringing her around. He--oh, here he is now."

The famous doctor was just coming downstairs. He saw us, but, I suppose, inasmuch as we did not belong to the Sutphen and Coleman set, ignored us. "Mrs. Sutphen will be all right now," he said rea.s.suringly as he drew on his gloves. "The nurse has arrived, and I have given her instructions what to do. And, by the way, my dear Sutphen, I should advise you to deal firmly with her in that matter about which her name is appearing in the papers. Women nowadays don't seem to realize the dangers they run in mixing in in all these reforms. I have ordered an a.n.a.lysis of both the milk and vichy, but that will do little good unless we can find out who poisoned it. And there are so many chances for things like that, life is so complex nowadays--"

He pa.s.sed out with scarcely a nod at us. Kennedy did not attempt to question him. He was thinking rapidly.

"Walter, we have no time to lose," he exclaimed, seizing a telephone that stood on a stand near by. "This is the time for action.

h.e.l.lo--Police Headquarters, First Deputy O'Connor, please."

As Kennedy waited I tried to figure out how it could have happened. I wondered whether it might not have been Mrs. Garrett. Would she stop at anything if she feared the loss of her favorite drug? But then there were so many others and so many ways of "getting" anybody who interfered with the drug traffic that it seemed impossible to figure it out by pure deduction.

"h.e.l.lo, O'Connor," I heard Kennedy say; "you read that story in the Star this morning about the drug fiends at that Broadway cabaret? Yes?

Well, Jameson and I wrote it. It's part of the drug war that Mrs.

Sutphen has been waging. O'Connor, she's been poisoned--oh, no--she's all right now. But I want you to send out and arrest Whitecap and that fellow Armstrong immediately. I'm going to put them through a scientific third degree up in the laboratory to-night. Thank you.

No--no matter how late it is, bring them up."

Dr. Coleman had gone long since, Mr. Sutphen had absolutely no interest further than the recovery of Mrs. Sutphen just now, and Mrs. Sutphen was resting quietly and could not be seen. Accordingly Kennedy and I hastened up to the laboratory to wait until O'Connor could "deliver the goods."

It was not long before one of O'Connor's men came in with Whitecap.

"While we're waiting," said Craig, "I wish you would just try this little cut-out puzzle."

I don't know what Whitecap thought, but I know I looked at Craig's invitation to "play blocks" as a joke scarcely higher in order than the number repet.i.tion of s...o...b..rd. Whitecap did it, however, sullenly, and under compulsion, in, I should say about two minutes.

"I have Armstrong here myself," called out the voice of our old friend O'Connor, as he burst into the room.

"Good!" exclaimed Kennedy. "I shall be ready for him in just a second.

Have Whitecap held here in the anteroom while you bring Armstrong into the laboratory. By the way, Walter, that was another of the Binet tests, putting a man at solving puzzles. It involves reflective judgment, one of the factors in executive ability. If Whitecap had been defective, it would have taken him five minutes to do that puzzle, if at all. So you see he is not in the cla.s.s with Miss Sawtelle. The test shows him to be shrewd. He doesn't even touch his own dope. Now for Armstrong."

I knew enough of the underworld to set Whitecap down, however, as a "lobbygow"--an agent for some one higher up, recruiting both the gangs and the ranks of street women.

Before us, as O'Connor led in Armstrong, was a little machine with a big black cylinder. By means of wires and electrodes Kennedy attached it to Armstrong's chest.

"Now, Armstrong," he began in an even tone, "I want you to tell the truth--the whole truth. You have been getting heroin tablets from Whitecap."

"Yes, sir," replied the dope fiend defiantly.
