According to Arthur Moses, the British Boys weekly “The Kinema Comic” ran a serial “The Amazing Exploits of Houdini” (“Written by Houdini Himself” – or so it says) and always began on page 6 and continued on to others. These were tales of pure fiction with maybe 2% fact thrown in. The weekly serials began with the v1n1 April 24, 1920 issue.
Harold Kellock says in his book “Houdini His Life-Story” (1928) that “The Kinema Comic” serial ran for seven years.
