Mona Moon is not your typical young lady in the 1930s. She is a scholarly cartographer by trade, an intrepid explorer by nature, and an ardent adventurer by heart. However, there is a serious problem.

Mona is eating breakfast with Jetta Dressler, her personal secretary, and Chloe, her poodle, when she receives a telegram from her dear friend, Lady Alice Morrell, begging her to hurry to England. It seems Lady Alice is receiving multiple death threats and thinks her life is in peril!

Alarmed that Lady Alice needs her help, Mona gathers her pistol, her steamer trunks, and Violet, her maid, to travel to Merry Old England. Once there, Mona encounters a nemesis she hasn’t seen for a very long time. She survived his attentions once. Will she be as lucky now?

Armed with her pistol, courage, and a bag of tricks, Mona is determined to save Lady Alice from harm, even if it means

she might die in the process. That’s how Mona does things in 1933.
