The disappearance of a young woman's father and a mysterious note years later after the strange regular annual delivery of valuable pearls to her puts Sherlock Holmes on the case.
Holmes compares Watson's accounts of their adventures as like working a love story into the Fifth Proposition of Euclid. This is the theorem that the angles opposite the equal sides of an isosceles triangle are themselves equal.
Dr. John Watson:
Very pretty young woman crossing the street. And I think she may be coming here.
Sherlock Holmes: Incidentally, I have glanced over your latest account of my work.
Dr. John Watson: Oh, yes?
Sherlock Holmes: Honestly, I cannot congratulate you upon it. Detection is, or ought to be, an exact science. ...
When Holmes, Watson and the police sail out on the police launch to lay in wait for the Aurora they sail upstream and under the Westminster Bridge as indicated by Big Ben and the Houses of Parliament in the background. Yet the Aurora was hidden at a ship yard near the Tower Bridge, and when the hunt begins the Tower of London is visible in the background. Both Tower Bridge and the Tower of London are located down the river from Westminster Bridge.
