Return To Paradise
When two Canadian sisters turned up dead in a Thailand hotel in 2012, local authorities suggested everything from drugs to food poisoning. But an updated investigation by the fifth estate points to new evidence that a highly toxic pesticide used in holiday hotels in Asia to control bedbugs may have caused their deaths. Mark Kelly reports on the risk to tourists.
