It's a decade since Spooks first appeared on our screens and we got caught up in the extraordinarily tense drama about MI5 agents. Now viewers have the chance to go back to those early days when we had no idea just how shocking the show was going to be – or how ruthlessly it would kill off our favourite characters along the way.
This was espionage drama that didn't just threaten our heroes, it made good on those threats at regular intervals, so you simply never knew who would survive from week to week. Fame was no guarantee of safety either: Matthew Macfadyen and Keeley Hawes starred in the early series but let's just say they didn't exactly last the whole ten years.
Sony Entertainment Television (Sky channel 157, Virgin channel 193) is showing the series from the start, beginning on 16 May and continuing every Wednesday at 10pm.
