"I have yet to learn," said Dennis, fully aware of the renewed look of
doubt in the faces of the men, "that a Red Cross nurse has any right to
pilfer a field letter-box, or that she usually carries a Browning pistol
for that purpose. Besides----" And at a venture he suddenly transferred
his grip from her left wrist to the nurse's headgear she wore.

"There you are!" he said, sternly triumphant, as the splendidly made red
wig came away and revealed the black hair beneath it. "Those handcuffs!"
And they closed with a snap on the wrists of the German spy.

Martique was sounding his horn as a signal that he was ready, but he was
not prepared for the sight that greeted his eyes as Dennis and the M.P.

Highlanders took the wood this morning, you know, but there's no sign of
Dennis. We can only hope for the best, Pater, and that is, that he is a
prisoner. Eh? What did you say?--I can't hear you--are you there?"

"Hold the wire a moment," came the response, delivered in a startled

The Great Push was still continuing without a check, and the Reedshires

Somebody came up to him for orders, and he gave them, and somebody else
