S11:É06 - S11:E06 - Days of Misrule

Barnaby and Jones are forced to take part in a team building exercise and Tom has plenty of problems dealing with the young, new, acting Chief Superintendent, John Cotton (Nick Fletcher). Following an explosion in a truck that had been stored in a truck depot, a body is soon discovered in a nearby lake, which turns out to be Alec Grainger, who had been seen arguing with James Parkes (Joseph Millson), the son of Colonel Matt Parkes (Tim Pigott-Smith). James appears to be involved in shady business deals and is blamed by his grandmother Caroline Halsey (Judy Parfitt) - and others - for the suicide of a woman he got pregnant two years before. Barnaby and Jones find themselves delving into a mixture of fraud, smuggling, and lies, trying to piece together the truth.
