"Tell you what, Leader, do you want to double your money?" "Double or quits?" "Of course double or quits. I'm having lunch at the Randolph Hotel in Oxford tomorrow with my uncle. If you can join us by one o'clock sharp tomorrow, I'll tear up this cheque and write you another for six thousand pounds" It is a bet Richard Gaunt cannot resist - all he has to do is walk from London to Oxford in under twelve hours. As an ex-soldier he is up to the challenge. But what starts as a harmless bet turns into something altogether different when Richard is taken hostage by a mysterious stranger, Mr Khan, who makes him a highly unusual proposal. What he offers in return could transform Richard's life. Traumatised by a tour of duty in Iraq, Richard feels he has nothing to lose. The love of his life won't speak to him, he has lost every job he ever had and his friends have vanished. He therefore decides to accept Khan's strange request - never imagining the places it will take him.
