S4E8 Dial M for Murdoch

A young switchboard operator accidentally listens in on a murder through the phone lines and immediately alerts Station House #4. When Murdoch investigates the address, he finds the place empty and no sign of a victim. However, he is intrigued by how spotless the room is and orders Crabtree to grab his murder bag. Clearly, this scene holds more secrets than it appears.
