The shades of red in Caravaggio's "Orfeo" have captivated Gertrude Stein, which is why Alice B. Toklas decides to knit her a scarf in that color. To match the tone precisely, she steps close to the painting and realizes that the paint is still wet. When she tries to report the forgery, she discovers a corpse in the office of the museum director. Thus begins the second mystery featuring Gertrude Stein and Alice B. Toklas, culminating in a dramatic showdown on the upper floor of the Arc de Triomphe. As in "A Murder is a Murder...", Johnny, the American friend of both women and the author's alter ego, is also involved, and once again, his unique talents—particularly his connections in the Parisian gay scene—prove to be crucial in solving the case. Sensitive readers will surely remember for a long time what passionate Frenchmen do with corkscrews.
