John Deegan

John Deegan is the main detective serving Carrigstown. Billy Meehan infamously laughed in John's face in several scenes during the early 2000's and it is thought that John has been offered in excess of €100 million by Paul Brennan to write a book documenting his interactions with the notorious and iconic gangster and publish it under Brennan Books.

Deegan is widely regarded as a disappointing pintman, known to be unable to put away more than 4/5 pints in any one sitting. As the cooler detective, Steve Yates serves to contrast Deegan at every opportunity and can, in any one sitting, put away in excess of 12 pints.
