Give Satisfaction

The timeline is extremely unclear. The stories mostly exist out of time (and out of continuity). The early stories were published in 1924 and the last in (I think) the late 60s and mentioned a protest march. Other than that, they are always more or less the same. Save for a few passing references, real world events don't take place in Wodehouse's world.

You might try asking at indeedsir. Or looking at the LJ indeedsir. They've got an excellent tagging system, and doubtless someone there has made one.
