A 'page turner" for sure. Thanks, Neil.
This puts me in mind of Paddy's (I think it was) posting several years ago, of the defrauded consumer who pursued relentlessly a crook who had defrauded him (also) in a PB sale . . . to the point, I seem to remember, of an arrest and a conviction.
If this miscreant had to pay for that "device" then it is sweet justice indeed, and all the more so for the author of the counter-scam to be able to "share" it.
