Toolbox Murders

Nell Burrows and her husband Steven move into an apartment at the Lusman Arms. But no sooner have they moved in and they are experiencing problems with poor maintenance, strange tenants, noise through the thin walls and renovations being conducted to the building. At the same time a masked man is stalking the tenants and killing them with various workman’s tools. Nell sees a number of suspicious things but these are dismissed after she calls the police over what she thinks is a violent argument in one apartment and this proves to only be an actor rehearsing his lines. As the murders continue, Nell is drawn to delve into the building’s past. She discovers that each floor has no Apartment 4 and that the original architect has designed the building with a series of occult symbols that lead to hidden chambers.
