Career
Though writing his adventure stories, science fiction and mystery novels under a long list of pseudonyms, the one he was best known for was Marton Taiga. However he death of his father and subsequent bankruptcy of the sporting goods store liberated Martti to pursue his literary career. During his heyday Marton Taiga was one of the best selling writers, if not the highest earner of them, but self-effacing to a fault, and thus nearly completely unknown to the general public as a person beyond his pseudonymous works.
The Kairala stories were published under the pseudonym M. Levä.
Another long running character of his was the intrepid newspaper reporter Kid Barrow (known by his nickname "Carrot"). A Tintinesque character.
