"Sorry," said Ember, hastily, "but shan't be able to. Fact is, I only ran in to see if you were comfortable--must get back to town immediately after dinner--friend's case at a critical stage."

"Everybody loves me and worries about my interesting condition--even you, wretched host that you are."

"I apologize."

"Don't; you needn't. I wouldn't for the world interfere with your desperate business. I'm really quite happy here--alone."

"Alone--I think you said?" Ember inquired after a brief pause.

"Alone," Whitaker reiterated firmly.

"I'm glad you like the place."

"It's most attractive, really.... I say, who are the Fiskes, anyway?"

"Well ... the Fiskes are the people who own the next cottage."

"I know, but--"

"Oh, I never troubled to inquire; have a hazy notion Fiske does something in Wall Street." Ember pa.s.sed smoothly over this flaw in his professional omniscience. "How did you happen to meet her?"

"Oh, mere accident. Over on the beach this morning. I slipped and hurt my ankle. She--ah--happened along and brought me home in her motor-boat."

On mature reflection, Whitaker had decided that it would be as well to edit his already sketchy explanation of all reference to the putative spy who wasn't Drummond; in other words, to let Ember's sleeping detective instincts lie. And with this private understanding with himself, he felt a little aggrieved because of the quarter toward which Ember presently saw fit to swing their talk.

"You haven't seen Drummond--or any signs of him, have you?"

"Eh--what?" Whitaker sat up, startled. "No, I ... er ... how should I?"

"I merely wondered. You see, I.... Well, to tell the truth, I took the liberty of camping on his trail, while in town, with the idea of serving him with notice to behave. But he'd antic.i.p.ated me, apparently; he'd cleared out of his accustomed haunts--got away clean. I couldn't find any trace of him."

"You're a swell sleuth," Whitaker commented critically.

"You be d.a.m.n'.... That's the true reason why I ran down to-day, when I really couldn't spare the time; I was a bit worried--afraid he'd maybe doped out my little scheme for keeping you out of harm's way."

"Oh, I say!" Whitaker expostulated, touched by this evidence of disinterested thoughtfulness. "You don't mean--"

"On the contrary, I firmly believe him responsible for that attack on you the other night. The man's a dangerous monomaniac; brooding over his self-wrought wrongs has made him such."

"You persuade yourself too much, old man. You set up an inference and idolize it as an immortal truth. Why, you had me going for a while. Only last night there was a fellow skulking round here, and I was just dippy enough, thanks to your influence, to think he resembled Drummond. But this morning I got a good look at him, and he's no more Drummond than you are."

"The h.e.l.l you say!" Ember sat up, eyes snapping. "Who was he then?"

"Simply a good-for-nothing vagabond--tramp."

"What'd he want?"

"Search me."

"But why the devil didn't you tell me this before?"

"You don't mean to say you attach any importance to the mere fact that an ordinary tramp--"

"I attach importance to many things that other people overlook. That's my artfulness. I don't suppose it has occurred to you that tramps follow the railroads, and that Long Island is free of the vermin for the simple reason that the Long Island Railroad doesn't lead anywhere any self-respecting tramp would care to go?"

"It's true--I hadn't thought of that. So that makes the appearance of a tramp in these parts a cir-spicious sus-c.u.mstance?"

"It does. Now tell me about him--everything."

So the truth would out, after all. Whitaker resignedly delivered himself of the tale of the mare's-nest--as he still regarded it. When he had come to the lame conclusion thereof, Ember yawned and rose.

"What are you going to do about it?" Whitaker inquired with irony.

"Wash and make myself fit to eat food," was the response. "I may possibly think a little. It's an exhilarating exercise which I don't hesitate to recommend to your distinguished consideration."

He was out of earshot, within the bungalow, before Whitaker could think up an adequately insolent retort. He could, however, do no less than smile incredulously at the beautiful world: so much, at least, he owed his self-respect.

He lolled comfortably, dreaming, forgetful of his cold-storage foot, serene in the a.s.surance that Ember was an alarmist, Drummond (if alive) to a degree hand-bound by his own misconduct, a wretched creature self-doomed to haunt the under-world, little potent either for good or for evil; while it was a certainty, Whitaker believed, that to-morrow's sun would find him able to be up and about--able to hobble, even if with difficulty, at least as much as the eighth of a mile.

Long shadows darkened athwart the clearing. The bay was quick with moving water, its wonderful deep blue shading to violet in the distant reaches. Beyond the golden arm of the barrier beach drifted the lazy purple sails of coastwise schooners. Gradually these blushed red, the golden arm took on a ruddy tinge, the bosom of the waters a translucent pink, mirroring the vast conflagration in the western skies.

Somewhere--not far away--a whippoorwill whistled with plaintive insistence.

In the deepening twilight a mental shadow came to cloud the brightness of Whitaker's confident contentment. He sat brooding and mumbling curses on the ache in his frost-bitten foot, and was more than slightly relieved when Sum Fat lighted the candles in the living-room and summoned Ember to help the invalid indoors.

Neither good food nor good company seemed able to mitigate this sudden seizure of despondency. He sat glooming over his plate and gla.s.s, the burden of his conversation _yea, yea_ and _nay, nay_; nor was anything of Ember's intermittent banter apparently able to educe the spirited retorts ordinarily to be expected of him.

His host diagnosed his complaint from beneath shrewd eyebrows.

"Whitaker," he said at length, "a pessimist has been defined as a dog that won't scratch."

"Well?" said the other sourly.

"Come on. Be a sport. Have a good scratch on me."

Whitaker grinned reluctantly and briefly.

"Where's my wife?" he demanded abruptly.

"How in blazes--!"

"There you are!" Whitaker complained. "You make great pretensions, and yet you fall down flat on your foolish face three times in less than as many hours. You don't know who the Fiskes are, you've lost track of your pet myth, Drummond, and you don't know where I can find my wife. And yet I'm expected to stand round with my mouth open, playing Dr. Watson to your Sherlock Holmes. I could go to that telephone and consult 'Information' to better advantage!"

"What you need," retorted the other, unmoved, "is a clairvoyant, not a detective. If you can't keep track of your trial marriages yourself...!"

He shrugged.

"Then you don't know--haven't the least idea where she is?"
