Cat, Richard and Charles are back for season two of The Rabbit Hole Detectives as the trio attempt to uncover as much as they can about the origin stories of stuff.

Each week they're given individual topics, told to disappear into the lab and not to come back until they've secured as many weird and wonderful stories as they possibly can. This week they deliver on all fronts as they tickle the ivories of history. But who will be coronated champion?

Don't forget, if you've a rabbit hole you'd like us to investigate, you can email us at [email protected]. And please leave us a review.
