From the publisher:

Stanford White was one of New York's most famous architects, having designed many mansions and the first Madison Square Garden. His influence on New York's look at the turn of the century was pervasive. As he became popular and in demand, he also became quite self-indulgent. He had a taste for budding young showgirls on Broadway, even setting up a private apartment to entertain them in, including a room with a red velvet swing. When he meets Evelyn Nesbit, an exquisite young nymph, cover girl, showgirl, inspiration for Charles Dana Gibson's "The Eternal Question" and for the later movie "The Girl in the Red Velvet Swing," he knows he's on to something special. However, Evelyn eventually marries a young Pittsburgh decadent heir with a dark side who develops a deep hatred for White and what he may or may not have done to her, setting up the most scandalous murder of the time.

Another fine entry in the Treasury of 20th Century Murder series.
