A petty man, he lost his position on the QE2 as a steward when he was caught stealing cash from a passenger. He drifted from con to con until, finally, he joined the Talamasca. Once a member, he set about rifling the order's secret files and stealing from the vaults. Using both his appreciable knowledge of computer systems and his psychic ability, he evaded discovery for a while, but was eventually found out and expelled from the order.
In the body of a twenty-six year old man, he followed Lestat around the world, and finally made the offer of this body, for a day and a night, to him. When Lestat agreed, Raglan absconded with his vampire body.
with the help of David Talbot, Lestat tracked him to the QE2, whence he was plundering island villas as the ship moved through the Caribbean on its winter cruise. Confronted, confounded, he stole Davids body(David was pushed into his), and managed to convince both the authorities and Lestat that he was in fact David.
However, when Lestat discovered the deception, he killed Raglan in a blind rage.
