The eccentric Olive Kettering swore someone was trying to harm her. Too bad no one listened, though plenty wanted her dead. When Olive is shot and killed, Mrs. Jeffries has no problem speaking her mind to see justice served.
Housekeeper Mrs. Jeffries and her employer, Inspector Gerald Witherspoon, investigate the drowning of the owner of a medical supply company, a man without greedy relatives or business rivals but a flair for amateur sleuthing that may have caused his murder.
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.
