In the May 27, 21013, issue of Antique Week, Robert Kyle has an article on the dangers of theft of antiques and collectibles coming from contractors and handymen. In fact, Kyle has been doing a series of articles on crimes, scams, etc. in the world of collecting, auctions, etc. and while they are unhappy issues, I highly recommend reading them precisely because there are, unfortunately, negative aspects in our lovely world.
A case in point, this recent case in the UK in which at least one of the parties involved in the thefts took tours of the historical places and homes in order to case them, later returning to burgle them.
