Jack Deam (DS Harken) and Sorcha Cusack (Nan Maide) also star in Father Brown together as Inspector Mallory and Mrs. McCarthy.
Actors David Burke and Tom Burke are father and son in real life.
Season Three finds Inspector Lynley driving a pristine maroon 1968 Bristol 410 grand-touring coupe. The car is notable for having a Chrysler 318-cid V8 and a Chrysler 3-speed automatic gearbox as well as having the spare wheel housed inside a compartment between the side door and the front wheel opening, accounting for the dramatically long bonnet (hood). Only 80-something such 410s were ever produced.
