The only mystery Charlotte and Jamie think they need to solve now, once and for all, is what they are to each other. But upon their arrival at Oxford, Charlotte is drawn into the case of a series of theatrical accidents, culminating in a young woman going missing on the night of a major performance. And no one  is talking. When Watson and Holmes join the theater program, the “accidents” start anew, giving them no choice but to throw themselves into the case. But as the complicated lines of friendship, love and loyalty blur, time is running out --- and tragedy waits in the wings.

It’s been a year since the shocking death of August Moriarty, and Jamie and Charlotte haven’t spoken. Jamie is going through the motions at Sherringford, trying to finish his senior year without incident. Charlotte is on the run, from Lucien Moriarty and from her own mistakes. She knows she isn’t safe to be around. She knows her Watson can’t forgive her. Holmes and Watson may not be looking to reconcile, but when strange things start happening, it’s clear that someone wants the team back together. Someone who wants to see one of them suffer and the other one dead.

Jamie Watson has always been intrigued by Charlotte Holmes. But the Holmes family has always been odd, and Charlotte is no exception. She’s inherited Sherlock’s volatility and some of his vices --- and when Jamie and Charlotte end up at the same Connecticut boarding school, Charlotte makes it clear she’s not looking for friends. But when a student they both have a history with dies under suspicious circumstances, Jamie can no longer afford to keep his distance. Danger is mounting and nowhere is safe --- and the only people they can trust are each other.
