In Leslie Charteris's The Saint's Getaway (1932) Simon Templar is on holiday with his beloved Patricia Holm when he gets mixed up with some stolen jewels.
This is the early version of the Saint when he's a crime-fighter but still a criminal as well, and he's reckless, irresponsible and irrepressible.
A rollicking roller-coaster ride to adventure.
