What the expert says...
Robert Carlyle Arrival Adds Major Plot Speculation
The introduction of Robert Carlyle has immediately influenced the betting markets, with his character priced at 3/1 to die during the series.
Given the show’s history of high-profile exits and dramatic arcs, it’s no surprise that new characters are often central to key plot developments.
At the same time, the market on a main character being arrested (2/1) suggests AC-12 could once again be targeting one of its own, which has been a recurring theme throughout the series.
Classic Line of Duty Twists Feature in Markets
Several of the specials lean into the show’s trademark twists and long-running theories.
Patricia Carmichael is 3/1 to become the new AC-12 boss, while the idea of a character faking their death sits at 6/1.
Meanwhile, long-standing fan speculation is reflected in the 10/1 odds on Ted Hastings being revealed as corrupt, a theory that has persisted across multiple seasons.
These markets highlight how much of the betting is driven by narrative expectations rather than pure probability.
