"Just a line to tell you I'm still alive, and hoping to remain so. You might write to me when you've time. In great haste, "Your affectionate cousin, "DENIS. "P.S. If you happen to see Miss FitzPeter, please give her my kind regards." This missive he addressed to Lady Margaret Clowes, at an address in Mayfair. She was only a very distant cousin of Allen's, and there was, on the face of it, no particular reason why he should have written to her at all. The regularity with which he had recently done so, therefore, coupled with the unfailing manner in which the postscript contained a polite message to Isobel FitzPeter, had given away to Margaret the true state of affairs; and because she liked and admired her shy cousin, she had contrived to keep his name not too insistently, and yet quite firmly, before Isobel's mind. She had determined, also, that when next Allen should come home on leave, she would engineer a meeting between them. If he had known this it would have filled him with joy, tempered with apprehension, for he was not blind to the fact that the Isobel he had known had developed into a new and rather formidable creature. She was now a public character, the last word in smartness, and sometimes rather a loud word at that. He felt that she was removed now to a sphere beyond his reach, for he was a very humble-minded person. Altogether, one way and another, he contrived to be acutely miserable when he had time to think about anything but his work, and he rather welcomed than otherwise the prospect of going back into the line. In due course an operation order came through from Battalion Headquarters, setting forth in minutest detail the times at which officers' valises would be packed and sent to the transport, mess-boxes made ready, blankets tied into bundles and delivered to the quartermaster, billets cleaned and platoons ready to move. When the time came there was the usual air of hopeless confusion, the accustomed mutual recriminations between conflicting or overlapping authorities; and in the end--also as usual--the battalion marched out at the appointed hour, leaving behind it very little to show that it had ever been there. The brigade was to take over the same part of the line it had last occupied; but in the three weeks' interval that had elapsed since they had been relieved, Hindenburg had carried out his famous "retirement according to plan," and our friends found themselves only just entering the shelled area about the point where, in the days of the Big Thaw, their front line had been.
