I have received many ingenious replies, but only one team gave the correct one.
The SOB Team (Margie and Sheila) hit the mark perfectly and the best I can do is to quote their answer literally:
–Place & Name of the ‘Ghost’: British Museum / British Museum Underground Station, no longer in use
–Stories, where it is noted Holmes went to the British Museum: HOUN, WIST
“I learned at the British Museum that he was a recognized authority upon the subject, and that the name of Vandeleur has been permanently attached to a certain moth which he had, in his Yorkshire days, been the first to describe.”
“One morning he spent in town, and I learned from a casual reference that he had visited the British Museum. Save for this one excursion, he spent his days in long, and often solitary, walks, or in chatting with a number of village gossips whose acquaintance he had cultivated.”
“I spent a morning in the British Museum reading up that and other points. Here is a quotation from Eckermann’s `Voodooism and the Negroid Religions’: – ”
–British Museum was a station on the London Underground, located in Holborn, central London. It was latterly served by the Central line and took its name from the nearby British Museum in Great Russell Street.
The station was opened by the Central London Railway in 1900. In 1933, with the expansion of Holborn station, less than 100 yards away, British Museum station was permanently closed. It was subsequently utilised as a military office and command post, but in 1989 the surface building was demolished and the remainder of the station is wholly disused.
–Ghost stations is the usual English translation for the German word Geisterbahnhöfe. This term was used to describe certain stations on Berlin’s U-Bahn and S-Bahn metro networks that were closed during the period of Berlin’s division during the Cold War. Since then, the term has come to be used to describe any disused underground station actively passed through by passenger trains, especially those on an underground railway line.
So, just a little clarification: I decided to cut this question out of the Hunt because the use of the term “ghost station” is not as familiar in English as is Geisterbahnhöfe to the Germans or “stazione fantasma” to the Italians. If you search the internet for a list of former London Underground stations you will probably find them described as “abandoned stations” or “disused stations”, not as “ghost stations”. This made the question very difficult indeed.
I must congratulate my fellow members of Uno Studio in Holmes who sent incredibly elaborate answers, digging deeply in the lore and tradition of English and German ghosts, in literature and otherwise. I kept telling them that it was easier than that… 🙂
Other valiant efforts were made by Robert Perret and Richard Olken. Thanks everybody for your answers.
We’re just about one week from the start of the Hunt. Keep your wits sharpened!
