Close, but Columbo comes out on top. And I have to say I'm pretty pleased with that, as he's definitely a favourite of mine. Yes, there were heaps of fictional detectives who weren't included in the poll, but I had to make some hard choices to avoid there being way too many options.

But still, I did neglect The Allosaurus, who won three write-in votes.
