As he talks with a colleague, Blair expresses how it has been his belief that human frailties are more important than circumstantial evidence. As if to prove his point, a new case is brought to him.
Word of a murder case comes to Blairs ears. At Clover Creek, two brothers have had a quarrel, and the one was cut out of the will. The will had been drawn up, but not signed, implicating that the surviving brother, Fred Sutton, had good motive for the murder, although he has an alibi. Blair sends his investigator out with the admonition to not arrest anybody just yet. Apparently the situation alone has alerted Blair’s instinct for foul play.
After a look at the boat that was involved, it is clear to the inspector that it was murder, it was rigged to cause the bottom to fall out and cause the passenger to fall through. The elaborate set up is explaned to Blair, and though on the surface, all signs point to Frank, Blair insists that it wasn’t the brother.
If not Frank, then who did it? Why does Blair think there’s someone else to suspect? To find out, stay tuned to the conclusion in the next episode.
