She Came Back

Set during WWII, Richard Jocelyn's wife has returned from the dead. Is it a case of mistaken identity? That is to be resolved. Throw in possible Nazi spies, murders, while it's not full of action, the mystery is interesting and there is an ongoing undercurrent of menace and threat. Maude Silver is a retired governess, become detective, who seems to do most of her work from her armchair as she knits wool socks for nephews and other family members. People who she meets, by chance, are drawn to her and she finds herself involved in this case almost by accident. Using her strong intuition, she provides valuable clues to the police; Sgt Abbott, who adores her and his boss, Inspector Lamb, who isn't quite so enamoured, but still doesn't mind using her skills at deduction.
