Toby Barker
Toby was a man who lived in London in the 19th century, who came for Professor Litefoot's aid after his wife Beryl had disappeared. This was evidently because she had visited Mrs Vanguard. He claimed that she had been acting strangely and screaming.
Professor Litefoot discovered her body in a burnt down house and told Toby that she had been the essence of the fire. Somehow she had burst into flame. Wanting explanations, they both visited Vanguard and discovered that Beryl was a victim of the consequences of bringing a spirit back from the dead.
Toby gave his life in the end (burst into flame), just so that he could be with his wife in the afterlife. (JAL The Spirit Trap)
