"A thoroughly researched and colorful account." -- Publishers Weekly

"[Deadly Valentines] is an engrossing look inside Al Capone's murderous ranks [and] a lively, detailed history of gangland Chicago." -- Kirkus Reviews

“Jeff Gusfield's Deadly Valentines is a wonderful exploration of not only Jack McGurn's life and violent career but also of that of Louise Rolfe herself. Written with the enthusiastic passion of a native Chicagoan, Gusfield's work does a wonderful job of clearing up much of the myth and misinformation surrounding McGurn and Rolfe, including in-depth examinations of their upbringing and their torrid yet all-too-brief life together. Chicago Valentines is not just a story of gangsters and guns, but of a love story that still captivates to this very day." --- Dan Waugh, author of Egan’s Rats and Gangs of St. Louis: Men of Respect

"Over the years, meaning beginning many years before I first met him, Jeff has been 'Pursuing' the subject of Jack McGurn. This stems from an almost life long interest Jeff has in the top killer in the Capone gang. During that time he has unearthed important public records pertaining to McGurn's life and death and spoken to various knowledgeable individuals about McGurn's life and career in a masterful attempt to find the facts about this man, his second wife and alibi Louise Rolfe, and the events related to them. Jeff is also an engaging storyteller." --- John Binder, author of The Chicago Outfit

“The life of McGurn, a misfired contender whose dereliction led to his demise; and Rolfe, the indecorous flapper and thwarted “IT Girl” whose man-baiting led her to the dark side of Valentine’s Day. Skilled researcher and empathetic writer Gusfield steers us into the private world of Al Capone and the pugilist-turned-killer, Jack McGurn – their clannish roots and gangland alliances – and explores the Machiavellian power that Capone directs toward McGurn and his failed dream of ringside glory. If the underworld ever produced an American tragedy, this is it.” --- Ellen Poulson, author, Don’t Call Us Molls: Women of the John Dillinger Gang and The Case Against Lucky Luciano: New York’s Most Sensational Vice TriaL

"Jeffrey Gusfield's Deadly Valentines is an encyclopedic love letter to the Roaring Twenties as embodied in its title characters, Jack McGurn and Louise Rolfe, each of whom succumbed to the seductive flash and drunken abandon of each other and the dark side of the American Dream. " --- Paula Uruburu, author of American Eve: Evelyn Nesbit, Stanford White: The Birth of the "It" Girl and the Crime of the Century

"You might think you know everything there is to know about Chicago’s wild Prohibition days, but Jeffrey Gusfield will prove otherwise. With Deadly Valentines, he vividly tells the twisted, yet somehow moving love story of an iconic American gangster and his sexy, nutty gun moll. Told with a driving, you-are-there narrative, it’s a rigorous, sometimes astonishing, and consistently entertaining performance." --- Douglas Perry, author of The Girls of Murder City: Fame, Lust, and the Beautiful Killers Who Inspired Chicago

“Authoritative, fast-moving, and affecting, Deadly Valentines tells a compelling true-life gangland saga that is loaded with action and, not least, the ache of romance. " --- Howard Blum, author of The Floor of Heaven: A True Tale of the Last Frontier and the Yukon Gold Rush and American Lightning: Terror, Mystery, the Birth of Hollywood, and the Crime of the Century
