"There's no resisting your colossal gall," he said, pa.s.sing into the adjoining room to get bed-clothing for his guest.

"I admit it," said Iff placidly.

As Staff returned, the telephone bell rang. In his surprise he paused with his arms full of sheets, blankets and pillows, and stared incredulously at his desk.

"What the deuce now?" he murmured.

"The quickest way to an answer to that," suggested Iff blandly, "is there." He indicated the telephone with an ample gesture. "Help yourself."

Dropping his burden on the divan, Staff seated himself at the desk and took up the receiver.

"h.e.l.lo?"

He started violently, recognising the voice that answered: "Mr. Staff?"

"Yes--"

"This is Miss Searle."

"I know," he stammered; "I--I knew your voice."

"Really?" The query was perfunctory. "Mr. Staff--I couldn't wait to tell you--I've just got in from a theatre and supper party with some friends."

"Yes," he said. "Where are you?"

Disregarding his question, the girl's voice continued quickly: "I wanted to see my hat and opened the bandbox. It wasn't my hat--it's the one you described--the one that--"

"I know," he interrupted; "I know all about that now."

"Yes," she went on hurriedly, unheeding his words. "I admired and examined it. It--there's something else."

"I know," he said again; "the Cadogan collar."

"Oh!" There was an accent of surprise in her voice. "Well, I've ordered a taxi, and I'm going to bring it to you right away. The thing's too valuable--"

"Miss Searle--"

"I'm afraid to keep it here. I wanted to find out if you were up--that's why I called."

"But, Miss Searle--"

"The taxi's waiting now. I'll be at your door in fifteen minutes."

"But--"

"Good-bye."

He heard the click as she hung up the receiver; and nothing more. With an exclamation of annoyance he swung round from the desk.

"Somebody coming?" enquired Iff brightly.

Staff eyed him with overt distrust. "Yes," he said reluctantly.

"Miss Searle bringing the evanescent collar, eh?"

Staff nodded curtly.

"Plagued nuisance," commented Iff. "And me wanting to go to sleep the worst I ever did."

"Don't let this keep you up," said Staff.

"But," Iff remonstrated, "you can't receive a lady in here with me asleep on your divan."

"I don't intend to," Staff told him bluntly. "I'm going to meet the taxi at the door, get into it with her, and take that infernal necklace directly to Miss Landis, at her hotel."

"The more I see of you," said Mr. Iff, removing his coat, "the more qualities I discover in you to excite my admiration and liking. As in this instance when with thoughtfulness for my comfort"--he tore from his neck the water-soaked rag that had been his collar--"you combine a prudent, not to say sagacious foresight, whereby you plan to place the Cadogan collar far beyond my reach in event I should turn out to be a gay deceiver."

By way of response, Staff found his hat and placed it handily on the table, went to his desk and took from one of its drawers a small revolver of efficient aspect, unloaded and reloaded it to satisfy himself it was in good working order--and of a sudden looked round suspiciously at Mr. Iff.

The latter, divested of his clothing and swathed in a dressing-gown several sizes too large for him, fulfilled his host's expectations by laughing openly at these warlike preparations.

"I infer," he said, "that you wouldn't be surprised to meet up with Cousin Arbuthnot before sunrise."

"I'm taking no chances," Staff announced with dignity.

"Well, if you should meet him, and if you mean what you act like, _and_ if that gun's any good, _and_ if you know how to use it," yawned Mr.

Iff, "you'll do me a favour and save me a heap of trouble into the bargain. _Good_ night."

He yawned again in a most business-like way, lay down, pulled a blanket up round his ears, turned his back to the light and was presently breathing with the sweet and steady regularity of a perfectly sound and sincere sleeper.

To make his rest the more comfortable, Staff turned off all the lights save that on his desk. Then he filled a pipe and sat down to envy the little man. The very name of sleep was music in his hearing, just then.

The minutes lagged on leaden wings. There was a great hush in the old house, and the street itself was quiet. Once or twice Staff caught himself nodding; then he would straighten up, steel his will and spur his senses to attention, waiting, listening, straining to catch the sound of an approaching taxi. He seemed to hear every imaginable night noise but that: the crash and whine of trolleys, the footsteps of a scattered handful of belated pedestrians, the infrequent windy roar of trains on the Third Avenue L, empty clapping of horses' hoofs on the asphalt ... the yowl of a sentimental tomcat ... a dull and distant grumble, vague, formless, like a long, unending roll of thunder down the horizon ... the swish and sough of waters breaking away from the flanks of the Autocratic ... and then, finally, like a tocsin, the sonorous, musical chiming of the grandfather's clock in the corner.

He found himself on his feet, rubbing his eyes, with a mouth dry as paper, a thumping heart, and a vague sense of emptiness in his middle.

Had he napped--slept? How long?... He stared, bewildered, groping blindly after his wandering wits....

The windows, that had been black oblongs in the illuminated walls, were filled with a cool and shapeless tone of grey. He reeled (rather than walked) to one of them and looked out.

The street below was vacant, desolate and uncannily silent, showing a harsh, unlovely countenance like the jaded mask of some sodden reveller, with bleary street-lamps for eyes--all mean and garish in the chilly dusk that foreruns dawn.

Hastily Staff consulted his watch.

Four o'clock!

It occurred to him that the watch needed winding, and he stood for several seconds twisting the stem-crown between thumb and forefinger while stupidly comprehending the fact that he must have been asleep between two and three hours.
