In this collection of six stories, the fireworks go off with a bang. There's a murky tale of blackmail at a candy convention; a chance to turn the tables on an unscrupulous real-estate broker; a confidence trickster with a keen grasp of maths; a scientific invention that is too good to be true; some respectable ladies with a secret to be kept; and a criminal lawyer who's perhaps too close to the criminals he represents. Simon Templar doesn't mean to start trouble, but how can he help responding to it when it falls into his lap?
