The Murder of Gambler Arnold Rothstein

My e-book considers possible connections between the murder of gambler Arnold Rothstein, the St. Valentine's Day Massacre in Chicago of 1929, and other gangland slayings. Rothstein's was killed in November 1928. A succession of murders followed including the Coral Gables, Florida murder of Fatty Walsh, formerly Rothstein's bodyguard. Were there connections? Sleuths of true crime in the 1920s and 1930s believed there were. My book looks at the Seabury and Crain inquiries into corruption in the millinery industry of New York. Rothstein had connections in the garment industry along with his many ties to gamblers.
