His appetites and evils made him a living legend
From the back:
He called himself The Gentleman From Hell
Stranger than any fiction, wilder than any fancy, is this true story of the wickedest man who ever lived. That’s how Ben Hogan billed himselfthe wickedest man on earth – and lived up to every evil boast. He made and threw away fortunes. He challenged any man living to stand up to his fists. He fought the heavyweight champion of the world — and beat him. He drank whisky by the gallon — and took his women by the dozen. Here, for the first time, is the authentic history of one of the most fabulous men America — or any other country — ever produced.
They were wild, these women of the hills, and Baxter was the man to tame them
For a dame, a fortune and fun they battled across Montana
Through canyons of night and neon he fled — cops, dames, and death at his heels
