Set in London in 1907, A Gentleman’s Guide to Love and Murder centers on Monty Navarro, a penniless clerk who is informed after the death of his mother that he is ninth in line to inherit the earldom of Highhurst, controlled by the wealthy D’Ysquith banking family. After the imperious ruling Lord dismisses Monty’s claim of being a relative, the eight D’Ysquiths ahead of young Mr. Navarro begin dying in natural and unnatural ways. (A single actor plays all the not-so-nice D'Ysquiths, adding to the merriment.) Meanwhile, Monty is trying to woo money-minded Sibella Hallward —until he finds himself drawn to young Phoebe D’Ysquith. How will all these convoluted storylines come together?
