Down and out private detective Harry Monday gets called in on a case and finds himself impersonating a psychiatrist. Three people murdered at the Shady Meadows Country Club, "A place where old polyester goes to die",  says Harry, after club members start dropping like divots on the duffer's course. And the club members aren't much saner than he is. A prima donna club president, an astrological moonchild, a Wall Street ad man are all dropping red herrings until Harry finds himself alone in the lobby, in the line of fire, in the dark.
