Pick of the week

Revisiting recent history through the eye-witness accounts of key participants is one of TV's strengths, as Channel 4 shows this week with two good examples of the genre. Station X, a four-part series on the wartime codebreakers of Bletchley Park, where the German Enigma machine's supposedly undecipherable messages were deciphered, begins on Tuesday (9.00). And on Sunday, Hostage (9.00) reaches part two (of three), covering the period from November 1985, when Oliver North first met an Iranian arms dealer in London, to January 1987 and Terry Waite's transformation from intermediary into hostage.
