Of the three novellas in this volume, two are absolute home runs, just complete triumphs. Wolfe has nothing, absolutely nothing to go on and he twists and turns circumstances until he's got something and runs it right out to the end of his genius. In the third he does the "send Saul to get something you don't tell the audience" trick but if you were paying attention you can figure it out yourself, which is everything we want in a mystery. What a delight!
