"Down by the shipping, along the Clydeside, are many barbers' shops, etc., owned by foreigners, and in one of these I think I have spotted an individual whose movements and behaviour entitle me to regard him as a spy. The party in question is a German of middle age, a man of remarkably refined appearance--in fact, not the class of man that one would ordinarily associate with a barber's shop. One has but to engage him in conversation to discover that he is no stupid foreigner, but a man very much up to date as regards our methods and things happening in this country. Our language, too, he speaks like a native, and, were it not for his markedly Teutonic features, he might pass for one of ourselves. "What excited my suspicions first regarding this personage was the fact that he was continually quizzing and putting to me questions regarding my employment of a decidedly delicate nature, and conversing freely on subjects about which I thought few people knew anything. I also noticed, when in his shop, that he was most lavish in his remarks to customers, especially to young engineers and draughtsmen who came to him from the neighbouring shipbuilding yards, leading them on to talk about matters concerning the Navy and shipbuilding; their work in the various engineering shops and drawing offices; and the time likely to be taken to complete this or that gunboat, etc. Indeed, with some of these young engineers and draughtsmen I have not failed to notice that he is particularly 'chummy,' and I also know, for a fact, that on several occasions he has been 'up town' with them, visiting music halls and theatres, and that they have spent many evenings together. On these occasions no doubt, under the influence of liquor, many confidences will have been exchanged, and many 'secrets' regarding work and methods indiscreetly revealed.
