"Caw must have had instructions," remarked Bullard presently. "One wonders how much Caw knows about his master's affairs."

Possibly Lancaster did not hear. He kept on staring at the message that had closed the door on his last hope. Carlotta's suggestion, or rather command, had been far from grateful to his inclinations, yet it had forced him towards the less of two evils, and for a few minutes he had imagined himself with Christopher's cheque in his pocket, immediate salvation and peace assured whatever it might cost him eventually. And now this telegram!

Impatiently Bullard touched him on the arm.

"Look here, Lancaster!—there is a train from St. Pancras at eleven, and it's now past ten. Pull yourself together."

"St. Pancras—eleven? To-night?" Lancaster checked himself.

"No, this morning! We shall be in Glasgow at eight, and a good car will run us down under a couple of hours…. Lancaster, for Heaven's sake, wake up! Can't you take in the situation? Listen! Point one: We saw the diamonds yesterday. Point two: Christopher died suddenly, sooner than even he expected, and the diamonds, in all probability, have not left the house—if he ever intended to send them elsewhere. They may even be still on the table or in the drawer! Point three: The sooner we discover their whereabouts the better, for if they are in the house we must act on Alan's will at once, though I'd have avoided that if possible. Alan knew nothing about the diamonds. Christopher distinctly stated that no one knows about them excepting ourselves and his servant. Well, if necessary, we must manage Caw, somehow. Now—"

"But—the clock—"

"Oh, damn the clock—mere tomfoolery! As for Alan's return, if you persist in doubting what I have already told you"—Bullard lowered his voice—"I shall be forced to introduce to you the man who—who saw Alan Craig die."

"Die!"

"Don't get hysterical. At this moment the one thing that matters is that we locate or lay hands on that green box."
