Detective Murdoch finds a bottle of nitroglycerin in a player's locker, which is then treated by everyone who handles it without the necessary care. Nitroglycerin is extremely dangerous and the slightest movement is enough to cause it to explode, and yet under this rough treatment it fails to detonate.
Henry speaks to Brackenreid and Murdoch of sledging by the cricket players. It is verbally insulting or intimidating an opposing player to break his concentration or confidence. However, the term wasn't coined before the 1960s.
Near the end of the episode, Murdoch incorrectly addresses the bishop as "Father" rather than as "Your Excellency".
