Jermyn Street in London is best known for its many gentlemen's outfitters, particularly its shirt-makers.
Although there is little hard evidence that Jermyn Street was a centre of money lending, it is possible to find several incidental references:
In Chapter 4 of E.W. Hornung's novel Mr. Justice Raffles, there is a reference to Raffles and his sidekick Bunny Manders going together to the jaws of Jermyn Street to visit the moneylender Mr Dan Levy;
Chapter 8 of The Picture of Dorian Gray by Oscar Wilde includes the following reference to money lenders in Jermyn Street:
... there were several very courteously worded communications from Jermyn Street money-lenders offering to advance any sum of money at a moment's notice and at the most reasonable rates of interest;
In a list of businesses of the City of Westminster to be found on the borough's website, it is noted that a money lender delightfully called Victor Honour was in business in Jermyn Street between 1875 and 1925.
