One caveat, I cannot understand those, like Crowder, who downplay the film Vincente Minnelli made of Humphrey's 1950s novel "Home from the Hill." Crowder pegs it as trash, but he should be more sympathetic; indeed, Minnelli's Home from the Hill is wonderful in ways Humphrey's novel never aspires to. Both are worthwhile, and the film is a masterwork.
But don't let that stop you from acquiring a copy of this book, one of the most enthralling literary biographies of the year.
