Clarence Wilkinson and Jennie Matheson are part-time agents with British Intelligence.
The series name given these adventures by the author or publisher is 'Wilkinson At War' and I have chosen to use that as well but I could have found ample justification to call it Wilkinson & Matheson. The time frame for the tales of these two very interesting people is the early days of the Second World War.
Wilkinson, at 52 years of age and "already the proud owner of a slowly expanding waistline", is an attorney at a prestigious London firm who also volunteers many evenings to fire-watch duties in the days of the Blitz. The many younger lawyers at the firm would be astonished to learn that the stodgy man they know as "Boring old Wilko", having an "almost babyish face [which] gave him the appearance of an eager, if elderly, schoolboy", had served with some distinction on the Western Front during the Great War and continued in the Intelligence Service for several years after the cessation of hostilities. He would have likely and willingly stayed doing that unsung 'lawyer by day, fire-watcher by night' work had an old friend from his previous service not needed someone with his skills to help in a matter when there was, literally, no one else.
Matheson, a modestly attractive woman in her mid-20s, comes to our attention in the unenviable role of patsy, albeit one far too intelligent to stay such for very long, no matter how much the handsome fellow wooing her for classified intelligence put on his not-inconsequential charm. When we meet her, she is working in a lowly position in the transport section of the War Office. She got there through hard work, tenacity, and a determination to be self-sufficient. She will not be the fool that her new love interest expected her to be and by turning on him, she will become a work partner with Wilkinson.
The two will prove to be a fascinating team taking on German spies and saboteurs working inside the U.K.
