S6·E7 A Clean Division

D.I. Burnside is delighted to be called out of a boring meeting at Stafford Row police station, especially as he thinks it's D.C. Carver with a lead on an important drugs case. Burnside is horrified to find, however, that Carver has been arrested for drink-driving by an over-zealous Stafford Row officer named P.C. Horden. Since Carver's police career is on the line, Burnside and Horden's more sympathetic colleagues manage to delay Carver's breath test for a while, and Carver eventually passes the breath test and is released.
