I think this whole think is an Act..
An intricate ruse put on by Digger to mask his recent spate of frivolous online eBay purchases and to keep it from Mrs Digger.
I fear that it has caused problems with him blaming his brother and even trying at one point to deceive his lovely Mum.
The whole thing reads like a bad 1939 Film Series with some Detective running around trying to solve the mystery. In fact it reads like the script of a Radio Series from a similar era...
Who is behind these random acts of Shirting? What drove them to such Shenanigans? Should they Stop right meow? I'm sure the answer is...
