His interest in adventure stories began at an early age with reading the books of: Daniel Defoe, Sir Henry Rider Haggard, Arthur Conan Doyle, Sir Thomas Malory, Robert Michael Ballantyne, Robert Louis Stevenson, Edgar Rice Burroughs, and Kenneth Grahame. He attended St. John's School, an inner city school that had its playground on the roof. On his first day at St. John's, at the age of ten, he had an experience that marked his potential as a writer. When given an assignment of writing a story about animals, he wrote about the bird that cleaned a crocodile's teeth. The teacher could not, and would not, believe that a ten year old could write that well. When young Brian refused to falsely say that he had copied the story, he was caned as "a liar". He had always loved to write, but it was only then, that he realized that he had a talent for writing.

Some teachers at St. John's proved to be good role models. This interest in poetry extended to Wordsworth, Tennyson, and Goldsmith. It was also at St. John's that Brian met a teacher, Alan Durband (who also taught two Beatles, Paul McCartney and George Harrison), who, more than thirty years later would bring about a major change in his life.

After Brian finished school at fifteen, he set out to find adventure as a merchant seaman. He travelled to many far away ports, including New York, Valparaiso, San Francisco, and Yokohama. Tiring of the lonely life of a sailor, he returned to Liverpool where he worked as a railway fireman, a longshoreman, a long-distance truck driver, a bus driver, a boxer, a bobby (Police Constable 216D), a postmaster, and a stand-up comic.
