During his stay in Britain, the "Sunday Times" initially put Vanunu up in a hotel in London close to the newspaper's premises, but shortly afterward, he was moved to what was considered a safer location: a lodge near Welwyn, in rural Hertfordshire, which was in an obscure location and accessed by a narrow road. Hounam considered it an excellent hiding place. During one foray into London together with a "Sunday Times" journalist, Vanunu encountered an Israeli friend, Yoram Bazak, and his girlfriend Dorit on Regent Street. They agreed to meet later. When they met, Bazak intensely questioned Vanunu on his views towards Israel's defense policy, and during the conversation, Vanunu told Bazak about the possibility of him publicly revealing secrets from Dimona to the British press, Bazak responded with a menacing threat. Hounam speculated that Vanunu's meeting with Bazak was no mere coincidence and that Bazak had been recruited by Mossad in an attempt to discover Vanunu's motives and try to dissuade him. Vanunu later grew bored of rural Hertfordshire and asked for a new location in London, and he was booked in the first hotel he had stayed in under a false name. Hounam speculated that as Oscar Guerrero, who had followed him and Vanunu to London, had already stayed there, Mossad likely had that hotel under surveillance.
