During the craze for cheap crime fiction in the late nineteenth century, Harlan Page Halsey wrote more than a hundred potboilers as Old Sleuth, a brilliant and gentlemanly master of disguise. The first begins on the beaches of Bay Ridge, with a corpse discovered in the ropes of a rowboat. The detective conducts intertwining investigations into this death, a burglary on Wall Street and the abduction of a young singer that take him from the financial and theater districts of Manhattan to a rural village on Staten Island, doggedly pursuing what really happened one moonless night outside a tavern on Shore Road.
