A second outing for Mickey Rawlings, the 1914 New York Giants' second-string second baseman (Murder at Fenway Park, 1994, not reviewed)--who's drafted into appearing in movie star Florence Hampton's latest film, only to discover her body washed up at Coney Island the morning after a heartfelt party. Florence, it turns out in the first of several nicely placed surprises, was trying to solve the two-year-old murder of her husband, and her death is only the first of a new round of skullduggery. And even though too little of the action involves the Giants' pennant run, patient readers will be rewarded by a homicide that really does take place, against all odds, at Ebbets Field. Well-judged period background (including a winsome role for Casey Stengel) enlivens a solid mystery.
