Some of the very best exports in the genre have been born across the pond, including long-running favorites such as Silent Witness and Midsomer Murders, with the latter ready to return for its remarkable 26th season. But not resting on their laurels, the best British networks are also consistently bringing new detective dramas to life, with one of the best to debut this decade coming in the form of Grace.
