I turned away with rage in my heart. What a cursed fool I had been not to wire from Groningen! I had fully intended to, but the extraordinary conversation I had had with Dicky Allerton had put everything else out of my head. At every hotel I had tried it had been the same story--Cooman's, the Maas, the Grand, all were full even to the bathrooms. If I had only wired.... As I passed out into the porch I bethought myself of the porter. A hotel porter had helped me out of a similar plight in Breslau once years ago. This porter, with his red, drink-sodden face and tarnished gold braid, did not promise well, so far as a recommendation for a lodging for the night was concerned. Still... I suppose it was my mind dwelling on my experience at Breslau that made me address the man in German. When one has been familiar with a foreign tongue from one's boyhood, it requires but a very slight mental impulse to drop into it. From such slight beginnings do great enterprises spring. If I had known the immense ramification of adventure that was to spread its roots from that simple question, I verily believe my heart would have failed me and I would have run forth into the night and the rain and roamed the streets till morning. Well, I found myself asking the man in German if he knew where I could get a room for the night. He shot a quick glance at me from under his reddened eyelids. "The gentleman would doubtless like a German house?" he queried. You may hardly credit it, but my interview with Dicky Allerton that afternoon had simply driven the war out of my mind. When one 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.
