"I figure prominently in this particular 'piece,'" snapped Grant. "May I ask your name, sir?"
"A wise precaution with suspicious characters," rejoined the other, smiling. Grant was suddenly reminded of a Japanese grinning at a joke, but he bent over a card which the stranger had whisked out of a waistcoat pocket. He read:
Mr. Charles F. Fueneaux,
Criminal Investigation Department,
New Scotland Yard, S.W.
He could not control himself. He gazed at Mr. Charles F. Furneaux with a surprise that was not altogether flattering.
"Did the Commissioner of Police send you in response to my telegram?" he said.
"That is what lawyers call a leading question," came the prompt retort. "And I hate lawyers. They darken understanding, and set honest men at loggerheads."
"But it happens to be very much to the point at this moment."
"Well, Mr. Grant, if you really press for an answer, it is 'Yes' and 'No.' The Commissioner received a certain telegram, but he may have acted on other grounds. Even Commissioners can be creatures of impulse, or expediency, just as the situation demands.
"You are here, at any rate."
"That is what legal jargon terms an admitted fact."
"Then you had better begin by assuming that I am no villain."
"It is assumed. It couldn't well be otherwise after the excellent character you have been given by this young lady."
"She, at least, will speak well of me, I do believe," said Grant, with a strange bitterness, for his heart was sore because of the seeming defection of his friend, the postmaster. "What I actually had in mind was the stupidity of the local policeman, who is convinced that I am both a criminal and a fool."
"The two are often synonymous," said Furneaux dryly. "But I acquitted you on both counts, Mr. Grant, on hearing, and even seeing, how you spent Monday evening."
Grant, who had cooled down considerably, found a hint of badinage in this comment.
"You have evidently been told that Miss Martin and I were star-gazing in the garden of my house," he said. "It happens to be true."
"Oh, yes. There was a very fine cluster of small stars in Canis Major, south of Sirius, that night."
"You know something about the constellations, then?" was the astonished query.
"Enough for the purposes of Scotland Yard," smirked Furneaux, who had checked P. C. Robinson's one-sided story by referring to Whitaker's Almanack. "It may relieve your mind if I tell you that I have never seen a real live astronomer in the dock. Venus and Mars are often in trouble, but their devoted observers seldom, if ever."
Grant warmed to this strange species of detective, though, if pressed for an instant decision, he would vastly have preferred that one of more orthodox style had been intrusted with an inquiry so vital to his own happiness and good repute. Eager, however, to pour forth his worries into any official ear, he brought back the talk to a definite channel.
"Will you come to my place?" he asked. "I have much to say. Let me assure you now, in Miss Martin's presence, that she is no more concerned in this ghastly business than any other young lady in the village."
"But she is interested. And you are. And I am. Why not discuss matters here, for the present, I mean? We have a glorious view of your house and grounds. We can see without being seen. None can overhear. I advise both of you to go thoroughly into this matter here and now."
Furneaux spoke emphatically. Even Doris put in a timid plea.
"Perhaps that would be the best thing to do," she said. "Mr. Furneaux has been most sympathetic. I am sure he understands things already in a way that is quite wonderful to me."
The very sound of her voice was comforting. Grant might have argued with the detective, but could not resist Doris. Without further demur he went through the whole story, giving precise details of events on the Monday night. Then the recital widened out into a history of his relations with Adelaide Melhuish. He omitted nothing. Doris gasped when she heard Superintendent Fowler's version of the view a coroner's jury might take of her presence in the garden of The Hollies at a late hour. But Grant did not spare her. He reasoned that she ought to be prepared for an ordeal which could not be avoided. He was governed by the astute belief that his very outspokenness in this respect would weaken the inferences which the police might otherwise draw from it.
Furneaux uttered never a word. He was a first-rate listener, though his behavior was most undetective-like, since he hardly looked at Grant or the girl, but seemed to devote his attention almost exclusively to the scenic panorama in front.
However, when Grant came to the somewhat strenuous passage-at-arms of the previous night between Ingerman and himself, the little man broke in at once.
"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."
"Did Mr. Grant draw any blind or curtains?"
"There are muslin curtains attached to each side of the window. One cannot see into the
