The Flashman books by George MacDonald Fraser is a very good source for Victorian history

I knew the books were popular worldwide, but didn't realise how popular until just now. Here's a link to "The Royal Flashman Society [small print: of Upper Canada ]":

Some people may be interested to know that Flashman first appeared as a (significant) character in Tom Brown's Schooldays.
