The Seven Dials Mystery

Not an ordinary mystery, this one is more “international spy” thing :-D

I didn't expect the twist. Good :-)

Reminds me a lot of Wodehouse. Slightly silly boys, very accomplished girls. I like that. :-D (Though, of course fatherly men try to keep girls out of the action, being such gentle, fragile things. Fainting and all.) Agatha didn't keep the girls safe, nor out of action. I like that, too :-D
