He was known as "Umbrella Mike": a hard man among the beautiful people. He moved among the elite of New York society with little notice, his sharply cocked fedora, his broad Irish face and his ever-present cigar setting him apart from the celebrities and socialites. Umbrella Mike is Michael Joseph Boyle, the corrupt leader of Chicago's most powerful union and himself a Chicago gangster on friendly terms with Al Capone. Passionate about high-class automobiles, Umbrella Mike was one of the few who could afford the luxury of racing during the hardship of the Depression. In 1937, dogged by adverse publicity and a barrage of disasters, the prestigious Vanderbilt Cup was held on Long Island. Brock Yates — noted editor, columnist and sports analyst and commentator — remarkably chronicles the dramatic events that unfolded during this most controversial of races — pitting against one another a Nazi poster child, a German-hating Swiss, and the brilliant American underdog who has a trick or two up his sleeve.
