Notice that book cover has an advertisement for "The Finished Mystery" that state it is "Pastor Russell's 7th volume, posthumerous publication"
The advertisement fails to mention that the book was also "posthumerously written" as well!
And if "The Finished Mystery" was indeed based upon Pastor Russell's writings, why is it that the sections of the 7th volume that were WRITTEN by George.H. Fischer removed in editions published after Fischer claimed that Judge Rutherford went to a burlesque show? That claim shouldn't have had anything to do with the book if its contents really were those of Charles Russell.
The whole Watchtower movement has been nothing but a bunch of smoke 'n mirrors since the beginning!
