She keeps house for Inspector Witherspoon . . . and keeps him on his toes. Everyone's awed by his Scotland Yard successes-but they don't know about his secret weapon. No matter how messy the murder or how dirty the deed, Mrs. Jeffries's polished detection skills are up to the task . . . proving that behind every great man there's a woman-and that a crimesolver's work is never done. A friendless old miser, banker Lawrence Boyd, is found dead at home. Called to the scene, Inspector Witherspoon is lucky to have Mrs. Jeffries's help-since the list of suspects includes just about everyone Boyd's ever met.
