Susan R. Matthews has been living with protagonist Andrej Koscuisko of her "Under Jurisdiction" series for a very long time (in a manner of speaking). Her wife is getting pretty tired of it, too, but he was there first. Maggie and Susan have only been married for thirty-seven years. Although her own branch of service during her two-year stint on active duty was Medical Administration (where being constantly mistaken for a nurse just because she was a female officer was a constant irritation - tells you how long ago that was), she has recently immersed herself in the history of German U-boats in World Wars I and II. In the absence of new English-language books on the subject she considers that her next logical step is to learn to read German.
