Mustela wanted to return to the 21st Century when he was known as John, but he wanted to take Suras with him. Mustela had been his name when he had lived as a Roman 2000 years earlier. He'd returned to Rome having been transported in time by Leonardo Da Vinci. He'd met his friend Suras again for the first time in all those years and had easily fallen into his old life with him. He continued to live as a Roman with all the rough edges of a man born and bred in Essex. The friend that he'd brought with him from the 21st Century had been sent back by Leonardo as a matter of urgency, because he had been badly beaten and was about to die. They have only just decided that the only way that they can find out if Sam survived the journey back, would be to go back themselves to look for him. Suras had never travelled in time before unlike Mustela who is already an old hand at the process. They finally return to Rome with a new friend who is an expert on Roman History. They all meet up with Caeser.
