Do you know your Master from your Mestor? Easy! But can you solve this month’s puzzle?

Wartime was Doctor Who’s first independent spin-off drama, starring John Levene as UNIT’s Sergeant Benton. First released direct to video in 1987, Wartime has now been released as part of Wartime Chronicles – a two-disc collector’s edition DVD set.

Also included on the set are the documentaries ReUNITed (a history of UNIT) and Jon Pertwee & UNIT Live on Stage (a UNIT panel from the 1986 convention PanoptiCon VII), as well as behind-the-scenes material and a brand-new introduction from Katy Manning (alias companion Jo Grant) and producer Keith Barnfather.

Wartime Chronicles is available now on Amazon from Koch Media, priced £14.99.

DWM has FIVE copies of the DVD set to give away to readers.
