has lived much among foreign peoples, one's mentality slips automatically into their skin. I was now thinking in German--at least so it seems to me when I look back upon that night--and I answered without reflecting. "I don't care where it is as long as I can get somewhere to sleep out of this infernal rain!" "The gentleman can have a good, clean bed at the Hotel Sixt in the little street they call the Vos in't Tuintje, on the canal behind the Bourse. The proprietress is a good German, jawohl ... Frau Anna Schratt her name is. The gentleman need only say he comes from Franz at the Bopparder Hof." I gave the man a gulden and bade him get me a cab. It was still pouring. As we rattled away over the glistening cobble-stones, my mind travelled back over the startling events of the day. My talk with old Dicky had given me such a mental jar that I found it at first wellnigh impossible to concentrate my thoughts. That's the worst of shell-shock. You think you are cured, you feel fit and well, and then suddenly the machinery of your mind checks and halts and creaks. Ever since I had left hospital convalescent after being wounded on the Somme ("gunshot wound in head and cerebral concussion" the doctors called it), I had trained myself, whenever my brain was _en panne_, to go back to the beginning of things and work slowly up to the present by methodical stages. Let's see then--I was "boarded" at Millbank and got three months' leave; then I did a month in the Little Johns' bungalow in Cornwall. There I got the letter from Dicky Allerton, who, before the war, had been in partnership with my brother Francis in the motor business at Coventry. Dicky had been with the Naval Division at Antwerp and was interned with the rest of the crowd when they crossed the Dutch frontier in those disastrous days of October, 1914. Dicky wrote from Groningen, just a line. Now that I was on leave, if I were fit to travel, would I come to Groningen and see him? "I have had a curious communication which seems to have to do with poor Francis," he added. That was all. My brain was still halting, so I turned to Francis. Here again I had to go back. Francis, rejected on all sides for active service, owing to what he scornfully used to call "the shirkers' ailment, varicose veins," had flatly declined to carry on with his motor business after Dicky had joined up, although their firm was doing government work. Finally, he had vanished into the maw of the War Office and all I knew was that he was "something on the Intelligence." More than this not even
