The queen of mail-order lingerie is the prime suspect in the search for the murderer of a loathsome evangelist. Brown (Texas! Chase, and Texas! Sage, etc.) finds New Orleans predictably steamy. French Silk, the hugely successful peekaboo lingerie catalog business, is awfully like the real-life peekaboo lingerie empire of Victoria's Secret; but instead of being run by an Ohio zillionaire, French Silk is the brainchild of Claire Laurent, a pretty Louisiana enterpreneuse, the only child of a genteelly disturbed New Orleans society belle and an Unnamed Father. For allegedly pandering to the lust of American manhood, French Silk and Miss Laurent have been for some time on the hit list of televangelist Jack Wilde. It is no surprise, then, that New Orleans assistant district attorney Robert Cassidy steers the investigation of Wilde's murder in Miss Laurent's direction. She's not the only suspect, of course. Wilde's white-trash wife and sensitive son had been exploring their step- relationship to an unhealthy extent. And Claire's pistol-packing supermodel business partner was carrying on an illicit affair with a handsome local congressman in the same neighborhood as the crime. And Claire's mamma has these disturbin' blackouts. Miss Laurent, however, seems to have the most strikes against her, and Mr. Cassidy follows her everywhere, his investigation immensely complicated by his lust for the suspect. The feeling is mutual. Glamorous lighting and soft-edged photography fail to disguise the paperback-romance roots of a totally unsurprising whodunit. (Literary Guild Dual Selection for June)
