Digging Up the Past - S4.E47

An excavator on a building site has uncovered some human remains, and Sgt. Cryer calls in C.I.D. Cryer is avoiding returning to the station, as his son Patrick is being charged with causing death by dangerous driving. Ch. Insp. Conway, Burnside and Roach have a word with Cryer, who is avoiding his family. On the building site, D.C. Dashwood and the S.O.C.O. wind up the site manager by saying it may have been a murder, although the bones are very old. A riot ensues as the men want to return to work. Burnside arrives and nicks the whole lot of them. The bones turn out to be from the Great Plague in 1665. P.C. Edwards is angry after being sold forger theatre tickets by Ramsey. Ramsey claims innocence, and the pair manage to locate the forgers. Unable to interest C.I.D. in the case, they investigate on their own and blow a joint Fraud Squad/U.S. Treasury operation to catch counterfeiters printing fake American dollars.
