Plot
Holmes and Watson are called to a house in Deptford, due to the concerns of a young woman about her safety. Several of her relatives have died in the past few years of heart attacks. A relative who trains canaries also lives in the house. Holmes is not able to detect anything amiss until he and Watson are en route home, but he suddenly solves the mystery and returns to Deptford to save the life of the young woman from a death by heart failure.

Allusions
This apocryphal story was inspired by the mention in "The Adventure of Black Peter" of Holmes's "arrest of Wilson, the notorious canary-trainer, which removed a plague-spot from the East-End of London." In this story, Wilson is not arrested, but this discrepancy is explained as an error due to Dr Watson.
