Against Odds by Lawrence L. Lynch

Believed to have been written by Chicago socialite, Emma Murdock Van Deventer, this detective story set at the World's Fair follows Carl Masters as he is in pursuit of international criminals Greenback Bob and Delbras. Conmen, lost handbags, jewel robberies, an adventuress... not to mention two missing young men and a murder, all come under the detective's eye. ( Lynne Thompson)
