Murdoch and Crabtree investigate the death of Reginald Chilton, the Member of Provincial Parliament from Toronto East who died from a fall from an upper floor at the Provincial legislature, Queen's Park. The guard on duty at the time, Briggs, swears he saw a ghost push Chilton over the railing. Samuel Jenkins of the Toronto Gazette informs the police that he was investigating Chilton's unscrupulous business dealings. Crabtree for his part wants to explore the supernatural elements of the case but Murdoch dissuades him. Dr. Grace says Chilton definitely died from the fall but it appears that he fell backwards over the balcony as if he had been pushed. A second man, Dr. Ansel Fraser, dies in a similar fashion and the police focus on the Provincial Secretary, Thaddeus Walsh. As far as the ghost is concerned Murdoch is convinced the apparitions are very human. Written by
