On Christmas Eve 1926, Eileen Walsh, a down on her luck single mother and local police sergeant Marquis Cummings, were caught having an extramarital romp and shot point bank on a grassy knoll near Brisbane's Bogo Road Goal.

But who murdered the adulterous couple? Was it a vengeful ex-husband? A long-suffering wife and loyal son? Perhaps a disgruntled co-worker or a jealous and forgotten lover?

Settle into your armchairs, put on your detective caps and join us as we dig through the facts and unravel one of Brisbane's oldest unsolved mysteries.
