"These youngsters are all the same," he complained querulously. "They will put flowers into their reports. It is always a beast of a job to make 'em understand that we want a fact plain and prompt. They can do it all right in the witness-box, but when they get a pen in their hand they fancy they're budding Shakespeares. The old hands know better." He passed from this outburst to particulars of what had happened. The Assistant Commissioner listened gravely, now and again interpolating a question or a suggestion. Foyle rapidly ran over the case, emphasising his points with a tap of his finger on the pile of papers. "We're progressing a little, though not so fast as I'd like. We know that Grell is alive, that he is in touch with Ivan Abramovitch and Lola Rachael--or the Princess Petrovska, as she calls herself. There is at least one other man in it--probably more. It's fairly certain that Grell knows who killed Harry Goldenburg even if he didn't do it himself. Goldenburg was apparently dressed in Grell's clothes before he was killed. It is clear now that the clothes were his own with Grell's belongings put in the pockets. A Mexican dagger was used. That may be or may not be of importance. Grell has travelled in Mexico. We have eliminated Ivan and Sir Ralph Fairfield as the actual murderers. Nor do the Princess Petrovska's finger-prints agree. I had Bolt take the finger-prints of all the servants in the house, so that we are sure that none of them actually committed the crime. All this narrows the investigation. If we find Grell we are in a fair way to finding the author of the murder." Sir Hilary Thornton stroked his 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."
