Mr. Campion's Farthing (Albert Campion, #20)

Murder and bad publicity stalk the inhabitants of Inglewood Turrets, the outrageous Victorian mansion where Lottie Cambric has recreated the best of the turn of the century for wealthy foreign culture-vultures. But when it becomes evident that this is a matter of highest state security the inimitable Mr. Campion takes a hand.

All books in the Albert Campion series are standalone titles and can be read in any order.
