But everything changes when reports of three kidnapped children reach the Greystone kids, and they're shocked by the startling similarities between themselves and these complete strangers. The other kids share their same first and middle names. They're the same ages. They even have identical birthdays. Who, exactly, are these strangers?

Before Chess, Emma, and Finn can question their mom about it, she takes off on a sudden work trip and leaves them in the care of Ms. Morales and her daughter, Natalie. But puzzling clues left behind lead to complex codes, hidden rooms, and a dangerous secret that will turn their world upside down.

Deeply bored by the lack of mental stimulus and the dull routine of existence, Sherlock Holmes is about to resort to his daily dose of cocaine when an elegantly dressed young woman called Mary Morstan enters his room and presents her case to him and Watson.

Now, with the last pearl, she has also received a message, telling her she is "a wronged woman" and asking for a meeting that very night outside the Lyceum Theatre. Will the great detective accompany her and help her unravel the mystery?
