Dee eventually left Elizabeth's service and went on a quest for additional knowledge in the deeper realms of the occult and supernatural. He aligned himself with several individuals who may have been charlatans, travelled through Europe and was accused of spying for the English crown. Upon his return to England, he found his home and library vandalised. He eventually returned to the Queen's service, but was turned away when she was succeeded by James I. He died in poverty in London and his gravesite is unknown.
