Wimsey passed a couple of hours agreeably with Lady Lubbock and crumpets and a dozen or so antiquated anatomical treatises. Presently Saunders returned with his report. The deposit was nothing more nor less than an ordinary brown paint and varnish of a kind well known to joiners and furniture-makers. It was a modern preparation, with nothing unusual about it; one might find it anywhere. It was not a floor-varnish—one would expect to meet it on a door or partition or something of that sort. The chemical formula followed.
"Not very helpful, I'm afraid," said Sir James.
"You never know your luck," replied Wimsey. "Would you be good enough to label the slide and sign your name to it, and to the analysis, and keep them both by you for reference in case they're wanted?"
"Sure thing. How do you want 'em labeled?"
"Well—put down 'Varnish from General Fentiman's left boot,' and 'Analysis of varnish from General Fentiman's left boot,' and the date, and I'll sign it, and you and Saunders can sign it, and then I think we shall be all right."
"Fentiman? Was that the old boy who died suddenly the other day?"
"It was. But it's no use looking at me with that child-like air of intelligent taking-notice, because I haven't got any gory yarn to spin. It's only a question of where the old man spent the night, if you must know."
"Curiouser and curiouser. Never mind, it's nothing to do with me. Perhaps when it's all over, you'll tell me what it's about. Meanwhile the labels shall go on. You, I take it, are ready to witness to the identity of the boot, and I can witness to having seen the varnish on the boot, and Saunders can witness that he removed the varnish from the boot and analyzed it and that this is the varnish he analyzed. All according to Cocker. Here you are. Sign here and here, and that will be eight-and-sixpence, please."
"It might be cheap at eight-and-sixpence," said Wimsey. "It might even turn out to be cheap at eight hundred and sixty quid—or eight thousand and sixty."
Sir James Lubbock looked properly thrilled.
