I know exactly how you feel Tom. Memories of going to a well known Doss House not that far from Bloomsbury pop to mind, when we turned a body over to find a whole pool of insects including maggots and cockroaches crawling out of the poor mans cavities, although i did not see it myself my partner swore a Rat ran out of the big hole in the mans stomach.. Back then (1982-) we had what was known as 'Smoke Bombs' which were set off in the closed Ambulance, then it was aired for a bit before we totally washed out. We still ended up with bites from the job itself, but nothing was left alive after! Do they not still use these to defumigate? - Just finished book BTW, great Job, hope you find time to read mine someday.
