A man turns up dead and naked in a trunk sent to the police department. The trunk was sent to Murdoch's boss Inspector Thomas Brackenreid. The man had been to see a friend who was creating motorized bicycles. They called the invention "mechanized bikes". This was before motorized cars. The man was supposed to get on a train I believe to Montreal but never boarded. Murdoch gets around on a bike and so do most of the actors and he looks like he is athletic slim body and skinny legs.
The dead man is examined by Dr Ogden who is the coroner in the these early episodes but later series Dr Grace does the job in the morgue of examining the dead people. It is interesting in how they come up with deductions of when and how a person died without all the science we have now. They show too much of dead body wounds, not like other series with dead people in morgues.
Anyway Inspector Thomas Brackenreid also gets a similar trunk at home with a dead body. Both men were killed in a similar way and the 2 dead men and Inspector Thomas Brackenreid had something to do with a case years earlier and the man threatened to get them all.
Inspector Thomas Brackenreid has a man brought in that might have some answers. He beats up the man in the cell more than once. I could not watch the violence after that. He did this in front of other police and Brackenreid thought he was entitled to beat the guy up, scream at him and get answers about the murders.
I don't know how it ended.
