December - Issue No. 1 released as 'The London Mystery Magazine', the volume is priced 2/6. The magazine is in the 'Digest Format' of 7⅜ by 5⅜ inches. The magazine is released in both the UK and the USA, the editions being the same except for the placement of regional advertising.
Founded and edited by Michael Hall, the magazine was and distributed by Hulton Press in the UK and Ziff Davies in the USA. With thanks to the Abbey National Building Society (the owners of the property), the address for the magazine is given as 221b Baker Street, the home of the fictional detective Sherlock Holmes.
Immediately, the estate of Sir Arthur Conan Doyle litigates against London Mystery Magazine for 'passing off' their magazine as being associated with Sherlock Holmes for using both the name and the address of the fictional character created by Doyle. The case was lost.
Magazine becomes bi-monthly from issue No. 2.
During April/May of 1950, Michael Hall released a French edition of the magazine with all of the stories translated. The first issue of the French edition was translated from the third issue of the UK edition (though one cartoon from issue 2 was also included). It seems that interest was low, as no further French editions appear to have been produced.
From issue No. 5, the magazine is renamed 'London Mystery Magazine'.
