CHAPTER V

Day had long dawned ere Foyle and his staff had finished their work at the great house in Grosvenor Gardens. There had been much to do, for every person who might possibly throw a light on the tragedy had to be questioned and requestioned. The place had been thoroughly searched from attic to cellar, for letters or for the jewels that, if Sir Ralph Fairfield were right, were missing.

Much more there would be to do, but for the moment they could go no further. Foyle returned wearily to Scotland Yard to learn that of the finger-prints on the dagger two were too blurred to serve for purposes of identification. He ordered the miniature to be photographed, and held a short consultation with the assistant commissioner. The watch kept for Ivan had so far been without avail. In the corridor, early as it was, a dozen journalists were waiting. Foyle submitted good-humouredly to their questions as they grouped themselves about his room.

"Yes. Of course, I'll let you know all about it," he protested. "I'll have the facts typed out for you, and you can embroider them yourselves. There's a description of a man we'd like to get hold of—not necessarily the murderer, but he might be an important witness. Be sure and put that in."

He always had an air of engaging candour when

dealing with newspaper men. Sometimes they were useful, and he never failed to supply them with just as much information about a case as would in any event leak out. That saved them trouble and made them grateful. He went away now to have the bare details of the murder put into shape. When he returned he held the diamond-set miniature in his hand.

"This has been left at the Lost Property Office," he declared unblushingly. "It's pretty valuable, so they've put it into our hands to find the owner. Any of you boys know the lady?"

Some of them examined it with polite interest. They were more concerned with the murder of a famous man. Lost trinkets were small beer at such time. Only Jerrold of The Wire made any suggestion.

"Reminds me of that Russian princess woman who's been staying at the Palatial, only it's too young for her. What's her name?—Petrovska, I think."

"Thanks," said Foyle; "it doesn't matter much. Ah, here's your stuff. Good-bye, boys, and don't worry me more than you can help. This thing is going to keep us pretty busy."
