"Hangman's Holiday" is a collection of short stories. There are twelve mysteries around the twenties and thirties England in this book, each stands alone but has a common feel; they are:
"The Image in the Mirror"
"The Incredible Elopement of Lord Peter Wimsey"
"The Queen's Square"
"The Necklace of Pearls"
"The Poisoned Dow '08"
"Sleuths on the Scent"
"Murder in the Morning"
"One too Many"
"Murder at Pentecost"
"The Man Who Knew How"
"The Fountain Plays"
It may be my perception but the mysteries get better and more intriguing as the next one appears. Then it is over.
I will not pull them apart as the fun is listening to them unfold.
You may also want to look for the unabridged tape, as the narrator is Ian Carmichael who played Lord Peter Wimsey. He changes his voice for the different people and you can tell the difference. There is a statement that tells you when the tape side ends.
