When Rogues Fall Out [PDF ebook] 

Meet Mr Toke, a dubious connoisseur of fine antiques who deals in fabulous objets d’art and doesn’t mind how he acquires them. From stealing bejewelled necklaces to rare antique clocks, Mr Toke cons a host of gullible individuals out of priceless heirlooms. But then he meets Mr Arthur Hughes and before long, the scam spirals out of control. Then there’s the case of the murdered Inspector Badger. Will Dr Thorndyke be able to solve the crime with his legendary incisive rationale? ’When Rogues Fall Out’ incorporates some wonderful conundrums to hoodwink and hinder the cleverest of crime readers.
