History, as a record of our past, is by no means a closed book. Seemingly intractable enigmas litter its pages, with "dirty deeds" prominent amongst them. From the "two princes in the tower" to a "grassy knoll" in downtown Dallas, this forum welcomes discussion on all such events - the what-, why-, how- and whodunits that have defied resolution throughout time.

From the construction of the pyramids in Egypt to the abandoned Mary Celeste, from the identity of the Sea Peoples to the Tunguskan event, our assumptions about what happened in our past are punctuated (and often punctured) by glaring gaps in our knowledge. This forum welcomes discussion on all such anomalies.
