Dixon Hawke was a fictional Scottish private detective living and working in Bath Street, Glasgow. After World War I, he moved to a flat on Dover Street in London, opposite the Ritz Hotel, near Picadilly. He was tall, "aquiline," and around 35 years old, with a "clear cut face."
He wore a dressing gown while lounging around his quarters, smoking a "blackened briar." He had a secret room where he kept a variety of clothes and disguises, and there was a secret passage out of his flat, which allowed him to go out unnoticed. He drove a powerful Sunbeam roadster.
Hawke was well respected, and well connected, sometimes dinning with the Prime Minister. Hawke's adventures took him around the world, to hidden civilizations, and pitted him against a wide array of enemies, including mad scientists, voodoo masters and more.
Between 1912 and 2000, Dixon Hawke appeared in more than 5500 stories,
giving him more published literary appearances than any other character.
He also appeared in Adventure Comics.
