The Fingerprint of Jack (A Time Savers Club Adventure Book 1)

Sam Henry had no idea how mysterious Mrs. Steers was when he and his Mom rented an apartment in her home. An old newspaper with a bloody fingerprint, a book of incantations, and a group known as The Time Savers Club take eleven-year-old Sam on an extraordinary trip back to 1888 London where he comes face to face with history's most notorious serial killer, Jack the Ripper. What Sam didn't realize was that he would find himself involved in a dangerous mission to save time.
