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, with a nice girlfriend he can't seem to fall for.
Charlotte is on the run, from Lucien Moriarty and from her own mistakes. No one has seen her since that fateful night on the lawn in Sussex--and Charlotte wants it that way. 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 has been quietly observing them both. Making plans. Biding their time.
Someone who wants to see one of them suffer and the other one dead.
