Joan's fourth mystery, MURDER REDRUM, is a mystery in which the clues are palindromes--words that can be read backward and forward, like "level". Set in 1923, the dry laws only add more confusion to an already addled, overworked police department. The solution of the crimes falls to a retired forensics cop, who is now a chinese restaurant chef, and his protégé, who has family problems of his own with the dry laws. The criminals' escape seems inconceivable, plus they have hostages. Only one thing is for sure. They aren't stopping for anything.
