Sherlock Holmes: Well, what of it, man? Has it come back to life and flapped off through the kitchen window?
Sherlock Holmes: Watson, we have been given a line of investigation which has been missed by the police and which a singular chance has placed in our hands. Now let us follow it to the bitter end.

Dr. Watson: Midnight. Merry Christmas, Holmes.
Sherlock Holmes: And to you, my dear friend.

Sherlock Holmes: Eh, well. You're quite right, Watson. Come, let's go.
