Inspector Singh is irate. He's been instructed to attend a Commonwealth conference on policing in London: a job for paper pushers, not real cops, as far as he is concerned.And as if that isn't bad enough, his wife is determined to come along to shop for souvenirs and visit previously unknown relatives. But it isn't long before the cold case that lands on Singh's ample lap turns into a hot potato and he has to outwit Scotland Yard, his wife and London's finest criminals to prevent more frightful executions from occurring on his watch - or indeed, from being added to their number.
