In Biggles Works It Out, Luis Leguez was a Mexican pilot and operative of Count Heinrich Horndorf's criminal gang known as "The White Prophets of Peace". Luis was formerly a gangster in Chicago. There, he apparently offended his associates as they "put him on the spot" i.e. put out a contract to kill him. This led Luis to seek refuge in Horndorf's gang. He was stationed at El Asile for some time and flew with Canton to the gang's secret landing strip in the Plaine de la Crau. Towards the end of the book, he flew the Count out of France in a bid to escape the French police. Some months later, Luis's body and that of the Count were found in the wreckage of a crashed aircraft on a Swiss mountainside.
