moustache doubtfully.

"That's all very well, Foyle, but Mr. Grell is hardly the sort of man to
commit murder. I gather that your suspicions point to him. Besides,
where is the motive?"

"Every man is the sort of man to commit murder," retorted the
superintendent quickly. "You can't class assassins. All murders must be
looked upon as problems in psychology. Mind you, I don't say that Grell
did have a hand in this murder. I am merely summing up the cold facts.
Why should he disappear? Why should he mix himself up with the shady
crew he is with--people who have twice tried to murder me, and who
knocked out and kidnapped Waverley? If we find him, we shall find the
murderer. That's why I wanted the description of Goldenburg sent out. It
makes work--I've got two men out of town now working on statements made
at Plymouth and Nottingham, which I feel sure will have no result, but
it gives us a sporting chance to nail him if he tries to leave the
country. Another line we're looking after is money. He's failed with
Fairfield. Lola had a try with Lady Eileen Meredith, who handed over her
jewels. We stepped in, bagged 'em, and gave 'em back to the Duke of
Burghley. All this means he'll have to make some desperate try for cash
soon."

"In fact it's check," commented Sir Hilary, who was something of a
chess-player. "Now you're manoeuvring for checkmate."

"Precisely," said Foyle. "I've been trying, too, to get hold of
something about Goldenburg. Neither we nor the American police have yet
been able to connect him up with Grell. We're still trying, though.
Sooner or later we shall get hold of something. And there's Lola. If we
could have got Wills to identify her as the veiled woman, we should have
had a very good excuse for arresting her in spite of her alibi. She's
the sort of woman who would prepare an alibi. We've not got any proof
that she knew Goldenburg. That's our great difficulty now--to link up
the various persons and find how they've been associated with each other
before. There's one thing, sir. I've managed to get the inquest
adjourned for a month, so we shan't have to make any premature
disclosures in evidence. The newspapers are still hanging about. They
got wind that something was happening at Malchester Row, and there were
a dozen or more men waiting for me when I came out, I told 'em that we'd
been trying to identify a woman and had failed. They'd have known that
anyway. They promised to be discreet. They're go
