Mycroft (Sherlock's brother) suggests he takes on a new case to take Watson's disappearance off his mind. Travelling to the city of York in Yorkshire, Sherlock, accompanied by Inspector Lestrade begins a new case. Neville St Clair went into town to buy Lego bricks for his children. His wife soon after traveled into town to pick up a parcel from the post office. Returning to her car she saw her husband looking out from a building window. Confused as to why her husband was there she entered the building with Inspector Lestrade to find her husband gone with only the Lego bricks to prove he was there. Since then, Neville St Clair has not been seen since. Vanished. Where is he? Murdered? On the run?
