“You despicable brute! Go to your bed and sleep—if you can!

CHAPTER XXIV

It was Monday morning. A church clock striking one reminded Gordon of this interesting fact. An hour had passed since Bobbie’s “good-night” had come to him through the closed door of his room.

“Good-night,” said Gordon.

“I wasn’t speaking to you,” snapped Bobbie.

He had been out all the evening interviewing Inspector Carslake, and the excursion had not been altogether profitable. Bobbie’s door closed. He heard the click of Diana’s lock being fastened. Dempsi passed, after rhapsodizing at the closed portals of Diana’s bower. From somewhere below came the snores of Julius Superbus.

Every exit from the house was closed, save one. The little casement in the big windows of The Study. Gordon had made a careful examination, for there was a possibility that Diana had taken the precaution of screwing it tight. But this she had neglected, satisfied probably with the presence in The Study of Mr. Superbus.

Twice Gordon had tiptoed to the door of his room and turned the handle. It was unlocked to-night. With Bobbie in the house Diana had relaxed her vigilance. Half-past-one chimed. Gordon got off the bed, put on his soiled collar and his coat and gathered up his shoes. He was penniless, but the servants at the hotel knew him, and he would be able to write a cheque on the hotel note-paper and get all the cash he wanted. And then he would return and deal with Mr. Dempsi. He had not yet decided as to the method of Dempsi’s death, but it would be painful. As for Heloise ... he hoped that she would be gone.

Extinguishing the light, he opened the door and listened. There was no sound, and, creeping down the stairs, he passed silently into The Study. Mr. Superbus was breathing regularly—the window rattled a little; the floor vibrated; but no other ill effects followed. As Gordon stood listening, the detective grunted and turned over on his side. The snores ceased—Julius was in a deeper sleep than ever. Now was his chance; yet he had not taken a step before he halted. A circle of light had appeared at the window. He waited, holding his breath. There was a rasping sound, and the casement opened. He saw the dark bulk of a figure wriggle through. A long pause, in which the newcomer was invisible, then the circle of light appeared again. This time on the safe.

A burglar! His first impulse was to leap at the man and grapple with him. His second was to approach with less commotion....
