Not one but two series travel to London for their season premieres tonight.
In an hourlong episode of Parks and Recreation (7 p.m., NBC/Ch. 5), Leslie is off to England to accept an award.
It makes more sense that Sherlock Holmes would go home to London in Elementary (9 p.m., CBS/Ch. 2). With Watson along for the ride, Sherlock confronts his past and his brother, Mycroft.
Elsewhere on TV ...
The Big Bang Theory (7 and 7:30 p.m., CBS/Ch. 2): Sheldon and Penny grow closer while Leonard is away; Leonard and Sheldon's friendship is tested. (Season premiere)
Marvel's Agents of S.H.I.E.L.D. (7 p.m., ABC/C. 4): If you missed the premiere on Tuesday, ABC is repeating it tonight.<
