Sorry to hear about your sad task OG.

The first port of call should be The DH Moth Club, which I am sure will have Stuart McKay’s ( Mr Moth) phone number. He lives in Berkhamsted, and so is even more likely to know of incidents so close to home.

Just put DH Moth Club in any search engine, and it will pull up their site.

Good Luck. Can you let us know if you find what you need?
