Wimsey ultimately discovers that Freke had lured Sir Reuben to his house with the promise of some inside financial information, and had murdered him there. Freke smuggled the body out onto the roof under cover of the cistern noise, took it into the hospital, and substituted it for that of a pauper which had been donated for dissection by the local workhouse. He then visited Sir Reuben's home to stage his disappearance, returned, carried the pauper's body over the flat roofs of the nearby houses and placed it in Thipps' bath, entering via a bathroom window that had been left open. As a joke, he added a pair of pince-nez that had by chance come into his possession. Returning to the hospital, he prepared Sir Reuben's body for dissection, giving it to his medical students for that purpose the next day.
