Troubleshooting private eye Ken Boon saddles up for the last time in this final series of the BAFTA-winning hit drama. Michael Elphick stars as Ken, the former fireman with a heart of gold and a passion for the Wild West, with David Daker as business partner and old friend Harry; Neil Morrissey is affable and ever-enthusiastic sidekick Rocky. Witty, heart-warming storylines and an array of prestigious guest stars ensured Boon was an instant ratings winner for ITV, and it remains a much-loved series to this day.

This time around, Ken and Harry are thrown into chaos by the departure of their secretary at Crawford Boon Security but there's a happier twist when Ken finds himself a sassy new Girl Friday in black leather, and Harry finds himself falling head over heels in love. Daniel Craig, Michael Kitchen, Leslie Phillips, John Nettles and Martin Jarvis are among the guest stars.
