S17·E41 Happy and Glorious (1)

The Section House is closing, and PC Reg Hollis is not only looking for a new place to live, he is also applying for a transfer to SO14 (the Royal Protection unit). He is about to buy a flat owned by an elderly friend, Doreen Tyler, but she changes her mind at the last minute, so he moves in with Tony Stamp temporarily. Hollis's intuition gives CID an important lead on a planned armed robbery, but his uniformed colleagues conspire to have Nick Klein organise the Section House closing party instead of him. Deciding to skip the party, Hollis goes to visit Doreen, but finds her dead in her flat. With no alibi, Hollis is the prime suspect for her murder, and he is suspended from duty. As Stamp and Klein work to find someone who can verify Hollis's whereabouts, CID discover a woman posing as Mrs Tyler's adopted daughter.
