Million Pound Bank Note

The story takes place in Victorian London, where two very rich, eccentric brothers give the penniless story protagonist, Henry Adams, one million pounds of money in the form of a single peerless bank note. Henry would not be easily able to exchange that note in the bank without being questioned about how he had come to it, charged with theft and arrested. He would also not be able to spend it since no ordinary person would be able to change it.
