It was always going to be The XYY Man for letter X, giving Andy the opportunity to finally take the cellophane off his DVD boxset. The series is about a repeat offender called Spider Scott, played by Stephen Yardley, who has an extra Y chromosome, believed at the time to make people more likely to commit crimes, particularly against property. On his tail is Don Henderson's Sergeant Bulman, who would go on to appear in Strangers and his own titular TV series.

When a prominent diplomat finds himself in a compromising situation with Zilda from Robots of Death, Spider is approached to steal a negative from the Chinese Legation in London. But its not altogether clear if Spider is being played. And when both South Africans and Rhodesians become involved its obvious that more is at stake than it first appears.

The series is directed by Ken Grieve (Destiny of the Daleks) and adapted from the books by Kenneth Royce. If Network DVD is to be trusted The XYY Man is a cult classic, but what do Andy and Martin make of it, and specifically, the first three-part story? And what effect will Martin just having had his COVID-19 jab have on proceedings?
