He called an orderly at last, finding the suspense unendurable, and gave him a scribbled line to carry to his wife.

"Is all well, sweetheart? Send back word by bearer," he wrote, and told the man not to return without an answer.

The orderly departed, and for a while Merryon devoted himself to the matter in hand, and crushed his anxiety into the background. But at the end of an hour he was chafing in a fever of impatience. What delayed the fellow? In Heaven's name, why was he so long?

Ghastly possibilities arose in his mind, fears unspeakable that he dared not face. He forced himself to attend to business, but the suspense was becoming intolerable. He began to realize that he could not stand it much longer.

He was nearing desperation when the colonel came unexpectedly upon the scene, unshaven and haggard as he was himself, but firm as a rock in the face of adversity.

He joined Merryon, and received the latter's report, grimly taciturn. They talked together for a space of needs and expediencies. The fell disease had got to be checked somehow. He spoke of recalling the officers on leave. There had been such a huge sick list that summer that they were reduced to less than half their normal strength.

"You're worth a good many," he said to Merryon, half-grudgingly, "but you can't work miracles. Besides, you've got—" He broke off abruptly. "How's your wife?"

"That's what I don't know, sir." Feverishly Merryon made answer. "I left her last night. She was well then. But since—I sent down an orderly over an hour ago. He's not come back."

"Confound it!" said the colonel, testily. "You'd better go yourself."

Merryon glanced swiftly round.
