DOUBLE DEALER

Double Dealer ($20.00; Feb.; 256 pp.; 1-57566-507-7) Those irrepressible twins, Nan and Bert Tatum, are up to their identical necks in murder again. The victim now is antiques dealer Franklin Haggerty, whose business practices are as sharp as his temper; the leading suspect is Bert’s daughter Ellie, who’d swapped legally charged accusations with him; and the range of whimsical/threatening/didactic adventures among the crowd of antique suspects is just what you’d expect from Nan and Bert’s first three cases (Double Cross, 1998, etc.).
