or God's sake, if you are an Englishman, help me!" That cry of despair, so subdued yet piercing in its intensity, reached Arthur Dalroy as he pressed close on the heels of an all-powerful escort in Lieutenant Karl von Halwig, of the Prussian Imperial Guard, at the ticket-barrier of the Friedrich Strasse Station on the night of Monday, 3rd August 1914. An officer's uniform is a passe-partout in Germany; the showy uniform of the Imperial Guard adds awe to authority. It may well be doubted if any other insignia of rank could have passed a companion in civilian attire so easily through the official cordon which barred the chief railway station at Berlin that night to all unauthorised persons.
