The man's testimonials were excellent upon all points excepting the one weakness before referred to, and I treated him quite unsuspectingly. Little did I know that when he made notes in shorthand they were in fact literal and verbatim reports of our entire conversation, made at the suggestion of the police and for their special benefit. I afterwards heard that detectives had helped to prepare the very code he brought to me and which he was so eager for me to substitute for one I had suggested. Had I been indiscreet, and had I given anything at all away, or had I trusted this man with any facts relating to or concerning those connected with my real employment, I would have been arrested on the spot. As it was, the police learned nothing which did not appear to them legitimate, in order, and most flattering to their country, to their countrymen, and to themselves. Remarkable as it may appear, it was, however, a fact that I was restless and uneasy. Instinct seemed to whisper in my ears, continually day and night, messages of warning that all was not well. The air seemed overcharged with electricity. It felt heavy, like an ominous calm preceding a violent storm. Yet, rack my brain as I would, I could not for the life of me fathom the depth of the mystery, nor could I trace its origin to any fountain-head. Meanwhile my new assistant entered upon his undertaking. In a few days he sent to me by code a detailed description of a sea engagement between German and English warships. It was the fight off the Dogger Bank in the North Sea, in April, 1915. In the course of the next six weeks, in addition to his proper work, arranging with outpost correspondent agents, he collected and forwarded at regular intervals a mass of interesting matter, all good newspaper copy, with many little tit-bits of special news which were most acceptable. But he would rub in items of local naval and military intelligence in spite of my repeated instructions to the contrary.
