This mystery isn't the traditional one - far from it. The mystery is that every Christmas our website turns up on the front page of Google for people searching for Thomas Merritt, a Cornish composer who died in 1908. We don't know why this happens, and we certainly didn't do anything to bring it about, but Google obviously moves in a mysterious way. Because of that, we always take care to keep a stock of Merritt's collection of Carols, which we send to customers all over the world.
Not much else of Thomas Merritt's music survives, but there's a little information to be found at http://www.bbc.co.uk/cornwall/content/articles/2008/05/20/history_thomasmerritt_feature.shtml
and you can buy a book of his Carols from a certain music shop in Bury St Edmunds.
