A Spy in the House book 1 of The Agency by Y.S. Lee

Very good used condition. Had an inscription in lead pencil in the first inside page which has been erased and is not very visible at all as seen in photos. Back cover description : sentenced as a thief at the age of 12 Mary Quinn is rescued from the gallows and taken to Mrs. Grimshaw‘s Academy for girls. Their Mary acquires a good education, fine manners, and a surprising opportunity. The school is the cover for the agency, top-secret core of female investigators with a reputation for results at 17 Mary’s given a test assignment infiltrating a rich merchants home in the guys of a ladies companion, and I’m covering his suspected fraud, but the Thorold household is full of dangerous secrets and people are not what they least of all ages 12 and up.
