"We took our finals together," said Hazlewood.

Sylvia went away quickly; if she had paused to compare this meeting with the first meeting in the railway carriage not yet three weeks ago, she should have broken down.

When Miss Potberry heard of her chief's arrival in Nish she insisted upon going to see him.

"But, my dear woman, he may be dying. What's the good of bothering him now? I'll find out whatever he can tell me. You must get ready to leave Nish. Pack up your things."

"He may be glad to dictate something," Miss Potberry argued. "Please let me come. I am anxious to report to Captain Hazlewood. I'm sure if you had told him that I was here he would have wished to see me."

Sylvia did not feel that she could contest anything; with Miss Potberry's help she burned the few papers that remained in the safe, together with the cipher, which glowed and smoldered in the basin for what seemed an interminable time. When not a single record of Hazlewood's presence in Serbia remained, Sylvia and Miss Potberry went back to the hospital.

"You've burned everything?" he asked.

Sylvia nodded.

"Is that a nurse? I can't see in this infernal candle-light, and I'm chockful of morphia, which makes my eye-lids twitch."

"It's I, Captain Hazlewood—Miss Potberry. I had instructions from the War Office to report to you. I was unfortunately delayed upon my journey, and when I arrived from Salonika you had left. Is there anything you would like done?"
