With great deliberation Robin selected a cigarette from his case, lit it, and walked out through the front door into the fresh air again. More than ever he felt the riddle of Hartley Parrish’s death weighing upon his mind.

His intuitive sense rebelled against the theory of suicide, despite the medical evidence, despite the revolver in the dead man’s hand, despite the detective’s assurance. And floating about in his brain, like the gossamer on the glistening bushes in the gardens, were broken threads of vague suspicions, of half-formed theories, leading from his hasty observations in the death chamber ...

In itself the death of Hartley Parrish left him cold. Yes, he must admit that. But the look in Mary Trevert’s eyes, as she had urged him to shield himself from the suspicion of having driven Hartley Parrish to his death, haunted him. Already dimly he was beginning to realize that Hartley Parrish in death might prove as insuperable a bar between him and Mary Trevert as ever he had been in life ...

She was now a wealthy woman. Hartley Parrish’s will had ensured that, he knew. But it was not the barrier of riches that Robin Greve feared. He had asked Mary Trevert to be his wife before there was any thought of her inheriting Parrish’s fortune. He derived a little consolation from that reflection. At least he could not appear as a fortune-hunter in her eyes. But, until he could clear himself of the suspicion lurking in Mary Trevert’s mind that he, Robin Greve, was in some way implicated in Hartley Parrish’s death, the dead man, he felt, would always stand between them. And so ...

Robin pitched the stump of his cigarette into a rose bush with a little gesture of resignation. Almost without knowing it, he had strolled into the rosery up a shallow flight of steps cut into the bank of green turf, which ran along the side of the house facing the library window to the corner of the house where it met the clipped box-hedge of the Pleasure Ground.

The rosery was a pleasant rectangle framed in a sort of rustic bower which in the summer was covered with superb roses of every hue and variety. Gravel paths intersected rose-beds cut into all manner of fantastic shapes where stood the slender shoots of the young rose-trees each with its tag setting forth its kind, for Hartley Parrish had been an enthusiastic amateur in this direction.

Robin turned round and faced the house. From his elevation he could look down into the library through the window with its shattered pane. He could see the gleaming polish on Hartley Parrish’s big desk and the great arm-chair pushed back as Hartley Parrish had pushed it from him just before his death.

The bare poles of the woodwork festooned with the black arms of the creeping roses, standing out dark in the fast falling winter evening, must, he reflected, have been the last view that Hartley Parrish had had before ...

But then he broke off his meditations abruptly. His eye had fallen on a narrow white patch standing out on one of the uprights supporting the clambering roses.

It was a stout young tree, the light brown bark left adhering to its surface. It was a long blaze on the bark on the side of the trunk which had caught his eye. Robin walked round the gravel path until he was within a foot of the pole to get a better view.
