Created by Belgian author and illustrator Michel Oleffe and Olivier Grenson in late 1989, he made his first comic book appearance in 1990.

As a teenager, he first studied away from his parents in the London's Slade School of Fine Art and then to Cambridge University where the young Carland differs in philosophy and Oriental and rare languages.

Although the quality of the studies to an academic career, he preferred to leave the University in 1914 to fight the enemies of his country on the battlefields of northern France during the World War I.

He entered Scotland Yard as an aspiring inspector in 1920, then quickly quit the police, which he deemed due to inappropriate methods, to open his own firm in Baker Street.

His serious pale face is recognized by his eternal frown-eyebrows, blue eyes, sideburns, black hair with a free cloth wick on his right forehead.

In the animated series, even if he is still sensitive to the suffering of others, upholding justice and fairness, he is sometimes depicted as a more frigid, cynical, and moody character.

He understood everything before the police and that is why Scotland Yard was the most frequently called upon only at the last end and as usual was silent while keeping his head cool even in the most horrible murders scenes.
