John Fletcher's Edwardian murder story is based on real events.
Frederick and Margaret Seddon take wealthy Mrs Barrow into their Islington home as a lodger.
The summer of 1911 proves scorchingly hot and when Mrs Barrow dies, leaving all her money to Fred, suspicions are aroused.
Was her death caused by the heatwave, or the arsenic-laced fly papers have something to do with it?
