Three novellas, from the time just before WWII when the Saint was still living in London at Cornwall House.
"The Miracle Tea Party" details what happens when Simon opens a packet of tea he has chanced upon, and finds it stuffed full of fifty pound notes.
"The Invisible Millionaire" has him investigating a murder mystery.
And finally, we have "The Affair of Hogsbotham". I've never met anyone named Hogsbotham (although my grandmother apparently went out with someone -- fortunately not my grandfather -- named Shufflebotham). Nonetheless, the pronouncements of a character of this name ("and with a face to match", according to Simon) are what lead the Saint unexpectedly into the third adventure, involving a bank robbery.
Patricia Holm and the Simon's faithful manservant Orace figure prominently, having of course both been with him since the very first Saint adventure, Meet the Tiger
. And for those who have (perhaps) wondered what happened to some of the other characters in that opus: a close reading reveals that the "moribund aunt" that Pat has to meet in the last story can only be Aunt Agatha.
I find myself re-reading the middle story less often than the others (although I'm not quite sure why), but the other two are well up to the usual Charteris standard of this period.
