- Sherlock Holmes: Oh, The Queen of Lambeth ? Its that pearly queen who's there so often with the organ grinder. It merely means to show the coin for identification and receive further instruction from her.
- Inspector Lestrade: For a glance at a coin, and a cheery good day the Queen of Lambeth will send you on your way. Arrive 8 am , Wednesday
- Inspector Lestrade: Holmes ?
- Sherlock Holmes: Hmm ?
- Inspector Lestrade: Holmes, are you awake ?
- Sherlock Holmes: Hmm, barely, Lestrade ,this is a ghastly hour, you know ?
- Inspector Lestrade: Of course, we've known for sometime at the Yard that there's been a leakage in the Foreign Office. What with Frederick Martinez in England, there must be some connection if only we knew what we stumbled upon? Holmes ?
- Sherlock Holmes: On top of the highest tower of all ,you can buy a souvenir with your coin. Tomorrow morning tell the vendor, you have no money smaller than the coin

- Sherlock Holmes: Well, we were very intent on our search, we took no precautions against being followed
- Sherlock Holmes: Perhaps not, however, we should want to enjoy our evening. It seems, of course, it may be our last.
