“Isidor G. Ingerman?” he cried. “Is he a tall, lanky, cadaverous, rather crooked person, with black hair turning gray, and an absurdly melodious voice?”

“You have described him without an unnecessary word,” said Grant.

Furneaux clicked his tongue in a peculiar fashion.

“Go on!” he said. “It’s a regular romance—quite in your line, Mr. Grant, of course, but none the less enthralling because, as you so happily phrased Miss Martin’s lesson in astronomy, it happens to be true.”

Grant was scrupulously fair to Ingerman. He admitted the “financier’s” adroitness of speech, and made clear the fact that if the visit had the levying of blackmail for its object such a possible outcome was only hinted at vaguely. Being a novelist, one whose temperament sought for sunshine rather than gloom in life, he wound up in lighter vein. The ruse which tricked P. C. Robinson into a breathless scamper of nearly a mile on a hot day in June was described with gusto. Doris, who knew the village constable well, laughed outright, while Furneaux cackled shrilly. None who might be watching the little group in that delightful garden, with its scent of old-world flowers and drone of bees, could have guessed that a grewsome tragedy formed their major theme.

The girl was the first to realize that even harmless merriment was in ill accord with the presence of death, for the body of Adelaide Melhuish lay within forty yards of the place where they stood.

“May I leave you now?” she inquired. “Father may be wanting help in the office.”

“I shan’t detain you more than a few seconds,” said Furneaux briskly. “On Monday evening you two young people parted at half past ten. How do you fix the time?”

Doris answered without hesitation:

“The large window of Mr. Grant’s study was open, and we both heard a clock in the hall chime the half-hour. I said, ‘Goodness me, is that half past ten?’ and started for home at once. Mr. Grant came with me as far as the bridge. When I reached my room, in exactly five minutes after leaving The Hollies, I stood at the open window—that window”—and she pointed to a dormer casement above the sitting-room—“and looked out. It was a particularly fine night, mild, but not very clear, as a slight mist often rises from the river after a hot day in summer. I may have been there about ten minutes, no longer, when I saw the study window of The Hollies thrown open, and Mr. Grant’s figure was silhouetted by the lamp behind him. He seemed to be listening for something, so I, who must have heard any unusual sound, listened too. There was nothing. I could hear the ripple of the river beneath the bridge, so everything was very still. After a minute, or two, perhaps—no longer—Mr. Grant went in, and closed the window. Then I went to bed.”
