The Holmes Cousins, Volume 2: The Moustache Society

Content : Here’s a new unusual case for Honorius and Mary Holmes!

"My sister Mary and I were contacted by a woman who suspects her husband of being unfaithful. Yet several details strike me as very strange and pique my curiosity. What if this seemingly ordinary adultery case is actually hiding a much bigger mystery? Our detective skills will be put to the test to untangle truth from lies! And I haven’t even mentioned my little cousin Sherlock, always underfoot and more annoying than ever… What a nuisance!"

Honorius Holmes, detective, has a reputation for solving the most complex cases alongside his sister Mary. The new case that occupies him seems, at first, quite ordinary: a lady suspects her husband, a bookseller, of being unfaithful.
But when Honorius follows the man, he is surprised to discover that he is part of a most unusual club: the Moustache Society. Even stranger, the organisation pays the bookseller handsomely to copy the Encyclopédie Universelle… In reality, this is a ruse to distract him while they dig a tunnel to the British Museum, located behind his bookshop!
The aim of the operation: to steal the Maharajas’ diamonds on display there. The Holmes cousins alert Scotland Yard, and the thief is caught on the very night of the heist.

A short, illustrated novel, easy to read, with a question-and-answer game for 10–12-year-olds.
