The Black Eagle Mystery

When Hollings Harland, a hot shot corporate lawyer from New York, plummets eighteen stories from a hall window of the Black Eagle Building onto Broadway below, suicide is the verdict. Part of an illegal cartel about to be exposed for trying to corner the copper market, Harland had just left an angry meeting with plutocrat Johnston Barker, also rumoured to be involved in the Copper Pool. Starting her own informal investigation by virtue of a friend who works on the seventeenth floor of the same building, sparky ex-switchboard girl turned part-time sleuth Molly Morgenthau Babbitts suspects murder, aided by her friend criminal lawyer Jack Reddy, his boss Mr. Whitney and her own husband, who is a reporter.
