Sum and Substance The Bill : Season 22 Episode 79

Turner and Nixon investigate an arson attack on a foster home, and suspect the boyfriend of one of the foster children may be responsible. Unconvinced that the man's watertight alibi is kosher, Turner continues to dig and discovers several links to the B&B fire that he and Nixon investigated several weeks before, and witnesses which place the suspect at the scene of both attacks. Meanwhile, after investigating a laptop theft, Hunter and Webb set up an operation to catch a scammer trying to sell on illegally smuggled banknotes from the US, which have been coated in black paint to avoid customs, after several of the supposed notes turn out to be nothing more than blank sheets of paper.
