You Can't Bluff the Sharp-Eyed Sister 4

A shrewd, young priestess-in-training is set a murder to solve in this new mystery manga from the creator of The Apothecary Diaries! By day, Chloe lives at a convent. By night, she's such a card shark, a holy knight ends up believing she has a rare, magical gift. What he doesn't know is, she just has sharp eyes and a quick wit--which she'll need when she's uprooted and dropped in the middle of a round of deadly palace intrigue! In a sleepy countryside church, Chloe plays the part of a prim and na�ve novice, studying to become a priestess. But when night falls, she sneaks out in disguise to win big money at cards! Despite her best efforts, word gets around, and one day a handsome young holy knight named Heraldo-known as a rising star in the capital-arrives to enlist her help. A murder two years ago threatens the stability of the kingdom, and Heraldo thinks this card shark in sister's clothes can solve it using her Gift-the rare blessing that allows someone to use magic. Little does Heraldo know, there's nothing supernatural about Chloe's winning streak. She's just got a quick wit, and sharp eyes! Will that be enough to survive the den of devils that is the royal palace?
