4 story's that are linked in some way. No. 1 was where a man went upstairs in his own home and just vanished. What I expected to be unusual and thought provoking turned out to be a long drawn out investigation and very drab. No. 2 a body in the bag mystery which is short, to the point and a great read. No. 3 about a vigilante who avenged women's abusive husband's. No. 4 uncovered drug dealings and a bent copper in the USA. 3&4 was nice to read.
