Ann Harrington is faced with scandal and the charge of murder when her husband, John, after his third nearly fatal coronary, dies -- but of cyanide. Her assist is Dr. Sargent, whose name will also be blackened by Harrington's private eye, Dorsey, and both are pursued by Mondo, who is trying to collect Dorsey's debts. Two, too wise, stepchildren, another killing, and Sargent and Ann can clinch. Connecticut and cashbox.
