He encountered Entwistle on the landing.

"Well?" he asked.

"He's just recovered consciousness," reported Philip. "A little light-headed, perhaps, and temperature up a bit. I'll come again at four. If you don't mind I'll arrange to stop here to-night."

"You're awfully good," said Peter, who had perhaps unconsciously taken upon himself the duties of deputy master of The Croft. "Well, lunch is awaiting you. Make yourself at home at my place. If there's anything you require don't hesitate to ask for it."

Entwistle had undertaken his self-imposed duties as sick-bed attendant with conscientious zeal; but he had also found time to make a complete investigation of the spy's papers, securing several that promised to become incriminating documents when subjected to professional scrutiny. At any rate, if he could be undisturbed he anticipated an interesting afternoon's search.

"I'll tell Barcroft all about it when I have completed the chain of evidence," he reflected. "He'll have a nasty shock, poor fellow, when he learns that his so-called pal tried to murder him. The whole thing's as plain as daylight to me; von Eitelwurmer meant to shoot him in the back, only the bursting of his gun saved Barcroft."

Left in charge of his treacherous friend, Barcroft found the patient had fallen asleep. Since nothing more was to be done Barcroft Senior took up a book, at the same time sighing for a pipe, a luxury that out of praiseworthy consideration for the injured man he had temporarily abandoned.

"By Jove!" said Peter to himself about an hour later. "That fire's getting low."

As silently as possible he heaped more coal upon the smouldering embers. Tending fires was not in his line. Often at home he would allow the study fire to die out simply through neglect to make use of the poker.

Somewhat anxiously he watched the gradually dimming glow. He was half-minded to ring for Mrs. Crumpet, until reflecting that the housekeeper at The Croft was evidently a person who made more noise in proportion to the work done than was desirable in the circumstances, he decided to tackle the recalcitrant fire himself.
