Martyn V. Halm lives in Amsterdam, with his wife Maaike, two children, two cats, and countless imaginary characters vying for attention.

When your protagonist is a seasoned killer, research can take you right up to Nietzsche’s abyss. Luckily, things get easier after the first kill. And, apart from being  an accomplished prevaricator, Martyn already possessed several skills that qualified him to write the Amsterdam Assassin Series.
