No Known Grave

After a difficult couple of years, Detective Inspector Tom Tyler has decided to make a new start in Ludlow, Shropshire. On the outskirts of town, St Anne's Convalescent Hospital, staffed by nursing sisters who are Anglican nuns, has been established in an old manor house to help victims of the war to recover. But when a horrifying double murder is discovered within the grounds, Tyler must figure out how it could have occurred in such a secluded and presumably impenetrable place.
