It was very rarely that he made a professional visit to a house without having a definite plan of attack carefully worked out. This was the first time he sought to gain entrance to a strange house on the mere chance of success. But the twenty thousand dollars in crisp notes tempted him. In his last affair he had netted this sum in notes of a similar denomination and he was superstitious enough to feel that this augured well for to-night’s success.

Careful as ever, Trent had made his alibis in case of failure. In one of his pockets was a pint flask of Bourbon, empty save for a dram of spirit. In another was a slip of paper containing the name of the house-holder who occupied a house with the same number as that of Williams, but on Ninety-fifth Street. Once before he had saved himself by this ruse. He had protested vigorously when detected by a footman that he was merely playing a practical joke on his old college chum who lived, as he thought, in this particular house, but was found to be on the next block. And in this case the emptied whiskey flask and the cheerful tipsiness of the amiable young man of fashion—Trent’s most successful pose—saved him.

In his pockets nothing would be found to incriminate him. He knew well the folly of carrying the automatic so beloved of screen or stage Raffles. In the first place, the sudden temptation to murder in a tight pinch, and in the second the Sullivan law. In the bamboo cane, carefully concealed, were slender rods of steel whose presence few would suspect. He had left such a cane in Senator Scrivener’s Fifth Avenue mansion when he was compelled to make an unrehearsed exit. Once he met the Senator coming down the steps of the Union Club with this cane in his hand. He chuckled to think what might be that worthy’s chagrin to know he had been carrying burglar’s tools with him.

As there was little light on the lower floor of Frederick Williams’ house, Trent let himself in cautiously. There was a dim hanging light which showed that the Williams idea of furnishing was in massive bad taste. At the rear of the hall were the kitchens. Under the swinging door he could see a bright light. The stairs were wide and did not creak. Carefully he ascended them and stood breathless in a foyer between the two main reception-rooms. There were voices in the rear room, which should, if Williams conformed to the majority of dwellers in such houses, be the dining-room. Big doors shut out view and sound until he crept nearer and peeped through a keyhole. He could see Williams sitting in a Turkish rocker smoking a cigar. There were two other men and all three chattered volubly in German. Unfortunately it was a tongue of which the listener knew almost nothing. Reasonably fluent in French, the comprehension of German was beyond him. There was a small safe in the corner and it was not closed. Trent felt certain that in it reposed those notes he had come for.

In the corner of the foyer was a carven teakwood table with a glass top, and on it was a large Boston fern. It would be easy enough to crouch there unobserved. The only possibility of discovery was the remote contingency that Williams and his friends might choose to use this foyer. But Trent had seen that it was not furnished as a sitting-room.

He had barely determined on his hiding place when he found the sudden necessity to use it. Williams arose quickly and advanced to the door. When he threw it open the path of light left the unbidden one completely obscured. The three men passed by him and entered the drawing-room in front. Trent caught a view of a luxuriously overfurnished room and a grand piano. Then Williams began to play a part of a Brahms sonata so well that Trent’s heart warmed toward him. But his appreciation of the master did not permit him to listen to the whole movement. He crept cautiously from his cover and into the room the three had just vacated. If there were other of Williams’ friends or family here Trent might be called upon to exercise his undoubted talents. One man he would not hesitate to attack since his working knowledge of jiu-jitsu was beyond the average. If there were two, attack would be useless in the absence of a revolver. But if the coast were clear—ah, then, a competence, all the golf and fishing he desired. There would be only the Countess to deal with at his leisure.

The room was empty, but the safe was closed! Williams was not devoid of caution. A glance at the thing showed Trent that in an uninterrupted half hour he could learn its secrets. But he could hardly be assured of that at nine o’clock at night. His very presence in the room was fraught with danger. The one door leading from it opened into a butler’s pantry from which a flight of stairs led into the kitchen part of the house. Downstairs he could hear faucets running. A dumbwaiter offered a way of escape if he were put to it. To the side of the dumbwaiter was a zinc-lined compartment used for drying dishes. It was four feet long and three in height and a shelf bisected it. This he took out carefully and placed upon the floor of the compartment, making an ample space for concealment. A radiator opened into it, giving the heat desired, and two iron gratings in the doors afforded Trent the opportunity to overhear what might be said. He satisfied himself that the doors opened noiselessly. The burglar’s rôle was not always an heroic one, he told himself, and thought of the popular misconception of such activities.

It must have been an hour later when he heard sounds in the adjoining room. By this time he was fighting against the drowsiness induced by the heat of his prison.

The swinging door between the butler’s pantry and the dining-room was thrown open and Williams came in. He leaned over the staircase and shouted something in German to some one in the kitchen, who answered him in the same tongue. There was the sound below of locking and bolting the doors. The servants had evidently been sent to bed.

When Williams went back to the other room the door between did not swing to by four or five inches. So far as Williams was concerned this carelessness was to cost him more than he guessed. Even in his hiding place the conversation was audible to Trent, although its meaning was incomprehensible.
