Yeomanry House is a military drill hall on Handel Street, Bloomsbury, London. The building was completed in 1913 for the Territorial Force Association. It has two halls, so was designed to accommodate two military units.
This is the location in episode 3 of Strike – The Cuckoo’s Calling where Cormoran Strike meets up with Lula Landry‘s half brother Jonah Agyeman. Strike questions Jonah about the night Lula was murdered, as Jonah was caught on CCTV prowling the street shortly before Lula fell to her death.
