Notes: The title page reprints the table of contents entry from the original magazine appearance and includes both the titles "Doctor Death" and "12 Must Die". The Cover reprints the original magazine cover and has both titles. The spine has only "Doctor Death". The copyright page abbreviates the title as "Dr. Death" in the copyright statement for this book. It also gives the 1935 copyright of 12 Must Die. The novel itself appears to be a facsimile reprint of the original magazine appearance and thus has only "12 Must Die" on the title page of the novel (as opposed to the book). Additionally the original magazine page numbering is given and does not match the page numbering of the rest of the book. The interior artist's signature is not clear enough to determine the full name. Reginald3 lists the title as "12 must die: a horror mystery straight from the devil's notebook."
