Colin Baker and Peter Purves

S3 E5: It’s a time travelling treasure hunt as the sixth Doctor Who, Colin Baker, pairs up with Blue Peter stalwart Peter Purves who played the first Doctor’s assistant. The two explore Herefordshire and Worcestershire in the TARDIS, disguised as a 1970 Morris Minor. Experts Will Axon and James Braxton will help them navigate, and on the way Colin once again comes up against his nemeses--the Daleks.
