The body of Dr. John R. Holstead, Gramercy Park inventor and owner of a wholesale drug house, is hurled out of an airplane above Market Street in Newark. Suspects are plentiful: his latest (and missing) formula is worth millions (as foreign agents well know), his nephew is suspected of peddling cocaine, his late best friend's grasping widow is in dire need of money, and some clues point to shifty smugglers. Detective Sergeant 'Pete' Tonelli of New York's homicide squad untangles the clues, leading to a lively climax and desperate battle. Death over Newark was published in 1933.
