On a fishing trip, at a little country inn, Holmes and Watson enjoy giving their minds a rest from crime fighting. They meet a pretty young girl, a young diplomat, and a pair of annoying canaries who are the target of murder by more than one person.
When the owner of the birds recognizes Holmes as the man who put him away for a crime years ago, he plans to be the first to act. From behind closed doors, there’s a murder confession, and a gunshot, but who was killed and why?
The girl is gone, as is the diplomat. Their connections are easy for Holmes to determine, but the confused Watson thinks the matter is still a mystery. Was the confession meant as a suicide? Where is the body? Holmes knows, but first he has to lay a small trap to expose the killer, and reveal how it was done.
