There are thousands of jihadi brides in refugee camps in the Middle East. Spider Shepherd is about to be sent on an extraordinary mission. There he will have to decide which of the women he meets are a threat, and which of them have useful information. But there is one bride he must take back to the UK whatever her circumstances. She is the wife of a notorious ISIS bombmaker, Salam Jaraf. The bombmaker will only tell MI5 what he knows if his wife and son are brought to him. But it soon becomes obvious that hostile forces are following Spider and Mrs Jaraf across Turkey.
