Dr. John Breland, a youngish Harley Street type, gets a mysterious new patient one day--chic, pregnant Sally-Ann Belmont, who claims to be a friend of Breland's pal Gerald Hinton. Then, soon after Sally-Ann's brief visit, she shows up again. . . during the men's-club stag party for Gerald, who's about to wed posh Elizabeth Lydney: Sally-Ann makes a theatrical entrance, announces that she's carrying Gerald's baby, swears vengeance, and disappears! Gerald (who swears he doesn't know her) follows in futile pursuit; a few hours later, the murdered body of the club's ladies'-room attendant is found; and, a couple of days later, Sally-Ann herself (a smalltime actress) turns up dead, also murdered, it seems, on the night of the stag party. What's going on? Is Gerald the culprit, trying to cover up a paternity-suit scandal? Breland, the sort-of-sleuth here, doesn't think so. Is someone using this elaborate hoax to frame Gerald, then? (Elizabeth's brother and her other suitor--who oppose the marriage to Gerald--are the probable suspects.) And what about Sally-Ann's genuine sugardaddies, both of whom happen to be members of Gerald's club? Well, the real motive involved is highly guessable--but the killer's identity, revealed after Breland almost becomes victim #3, is a modest surprise. Another solid, small-scale puzzle from the author of An Ad for Murder.
