When Henry is "shot" at the bus stop, blood appears on his jacket, but there is obviously no bullet hole.
Early on, when Templar has checked into a hotel established to be Stevenage, a London Transport double decker passes sedately along the road outside.
About one-quarter of the way into the episode, Templar is stopped at a security gate. After he is allowed into the premises with the security guard sitting in the passenger seat, a 5 m.p.h. speed limit sign is prominently seen. Templar's Volvo slowly proceeds, yet the car can be heard shifting into second gear and accelerating.
Magda Vamoff is supposedly Hungarian but it's not a Hungarian name, and Dawn Addams who plays her doesn't sound remotely Hungarian.
Simon tells Magda that Nick was shot with "only two bullets this time". However, he was only shot one time when he was murdered.
