Imagine the scene; you visit your shed and notice the plastic clips you placed on the side bench have been collected up and put into an tub of peanuts for the birds. You empty the ice cream tub. Next morning everything has been placed back in the tub, alongside screws, nuts and bolts. Must be a ghost, right?

Is a pandemic the best time to develop your zombie apocalypse plan? We can learn a surprising amount from the current situation.

Avid readers of crime fiction will be familiar with the ‘little grey cells’ of Hercule Poirot and Sherlock Holmes’ examination of trace evidence.
