Daily UI: 404: Page Not Found

Footmarks are 404 for a Poirot fan club website!
A 404 page is meant to show something a broken link or an address that doesn't "belong" to the website.

So, I thought, what might be considered as something out of place at a "Hercule Poirot" fan club page, and Poirot's disdain for footmarks and traditional detective methods immediately came to mind. Something that has no place in Poirot's investigative methods.
