Between 1933 and the 1950s, not much new information regarding Thomson’s death was brought forward by researchers. Most of the speculation regarding his death was self-published by amateur historians who had a strong interest in the case.

Research was helping to compel changes in theories regarding the Thomson tragedy. For instance, Blodwen Davies independently published a book on Thomson that offered a substantially different understanding regarding his death than her 1930 text (an edited version of this book would be reprinted in 1967, and is quoted from in the Investigations 1966-1978 section).
