The Case of Spiv’s Secret by Anthony Parsons was an entry in the Sexton Blake Library series, and came in 1950 from British publishing company Amalgamated Press. The Sexton Blake Library is what was known as a story paper, basically a magazine with illustrations, and this one appeared two to four times a month, starting all the way back in 1915 and continuing until 1968, which is an amazing run. We had to look up the word “spiv”—with serious trepidation. But it turned out to be relatively innocuous. A spiv can be a flashy dresser, but its other definition—which we suspect is Parsons’ usage here—is a sort of petty or low-class criminal. The artist on this is Eric Parker. You can see a few more Sexton Blake titles here, here, and here.
Obviously the poor guy tripped and fell, breaking every bone in his body and bashing his brains out. Maybe someone up there saw it.
