Zip Nolan was a Highway Patrolman who for some reason never adequately explained in records of his adventures frequently seemed to operate in England in the 1950's and 1960's. He was an accomplished detective.

The original Zip Nolan, drawn by Roberto Diso.

In later years, Nolan became a Special Forces operative serving in Vietnam, Iran and Kuwait (he had also served in Korea in the 1950's) and later an agent of the CIA. He was sent back to Britain to investigate possible security breaches at Castle Baaleskine, a remote location in Scotland which was being used as a prison for powered or otherwise unusual individuals. Sadly, Nolan's own arroganmce aside, he proved ineffectual in preventing a mass breakout.

Written at times by Michael Moorcock, Zip Nolan originally appeared in the British anthology comic 'Lion' and various Lion Annuals, published by IPC from the early 1950's to the early 1970's.
