The Secret of the Samurai is a classic mystery adventure comic in the Franco-Belgian school of bande dessinée as developed by Hergé, Edgar P. Jacobs, Yves Chaland and many others, though the story has a very British setting.

The strip was originally published in four episodes in the weekly comic, The Phoenix (nos. 75-78, June 2013) - you can buy back issues here and there's a bundle of all four 'Samurai' issues here. See the full cast of characters here.
