Murdoch Mysteries S04E06 - Dead End Street

Murdoch makes a surprising discovery at a dolls house fair: a made-to-scale diorama of a cul-de-sac Toronto street replete with miniature residents. In one of the houses, the artist has placed a hand firing a gun. This is no ordinary model - it's a crime scene. Murdoch finds the creator of the streetscape, an autistic 19-year-old, Lydia, who communicates best through model building. No one has reported a murder yet, but using the model's intricate clues left by Lydia, Murdoch discovers that someone indeed has been murdered – but what happened and why? Someone is far from happy by his investigations, and things begin to get even more sinister in the neighbourhood.
