Key passages

  • It is a capital mistake to theorize in advance of the facts.

    Making assumptions without evidence is a fundamental error.

    Holmes advises against premature conclusions during the investigation.

  • Unless its recovery can be attended with the utmost secrecy, then it may as well not be recovered at all, for all that is aimed at by those who have taken it is that its contents should be generally known.

    If the letter is not recovered secretly, its recovery is pointless because the thieves want it publicized.

    The Prime Minister explains the need for discretion in the case.
