John Raines entered his flat at dawn after a long night of drinking, tossed his keys on the dresser and stumbled off to get a shower. A rattle at the door handle followed by the creaking hinges brought him back in a flash, armed with a toilet plunger, to confront an intruder. The man who entered was shuffling through a stack of junk mail and idly tossed his keys right on top of John's. When he looked up, the shock registered on his face mirrored John's own: they were perfect twins.
The only difference was that the man who entered was better dressed and much less drunk. To make matters more confusing, both men could offer proof that they were both John Raines and had both rented the same flat exactly three months earlier. Shocking as this may be, what happened next would change the two men's lives forever.
