Paul Rocher is an agent with British Intelligence.
Known as the Red Wolf of Arabia, Rocher, though an Englishman, is every bit an Arab. His knowledge of the terrain of the Arabian Peninsula is certainly as good as its citizens and usually considerably better. While it is never expressly stated that he has been to virtually every community on that huge tract of land, it would be a safe bet based on his displayed experience to go with his having come close. This includes the holy cities of Mecca and Medina, the former being supposedly off limits to nonbelievers.
Despite there being a good number of short adventures written about Rocher, he is surpisingly a mystery. How he came to be so firmly entrenched in the Middle East is never explained and how he got so well connected with the powers that be in so many parts of the region is also unknown. What is known is that he is both of those - entrenched and well connected. British governors and local police commanders routinely ask for his help and in return often readily provide their resources. Still, most of the missions that Rocher undertakes invariably putting himself in harm's way and occasionally paying for it.
When not chasing down gun runners or saboteurs or assassins, Rocher is often found in establishments where he can either enjoy listening to good music on the piano or, if no is available, providing it himself. From the comments made by others, Rocher is very much a virtuoso and apparently had career potential in that industry. It is hard to imagine, though, Rocher living in a city for long as his love of the immensely open deserts like the Sahara in Africa and the Empty Quarter in Saudi Arabia is just too great.
One very important fact about Rocher is the reason for his being known as the Red Wolf. Though Rocher's skin is naturally darkened by so many years spent in the sun, his bright red hair shows instantly that he is not from around these parts and there are more than one occasion when having his keffiyeh pulled off his head has revealed his identity. Invariably, he takes such dangers with a customary laugh at both himself and his fates.
Note: in the American versions, the man was known as Paul Rodgers but since the British versions came technically first, that is the name I have chosen to use.
