S2·E1 Room With a View

Retired music hall singer Lettie Ross witnesses a murder in the empty house opposite her flat, but when police and her daughter are dismissive, she calls in Eddie. His investigations lead to Duke Winsor, a slum landlord who has just purchased the house, and Alan Fuller, another potential buyer - who proves to be the victim. In the event the basement flat in Lettie's block, leased to concert performers, is the key to the affair.
