Six strangely related stories about six encounters that could or should have never happened. A post mortem encounter with a clerk who has a most bizarre offer; an elusive encounter with oneself, only decades older; a seemingly innocent encounter with a bookshop visitor who is desperately looking for an ordinary SF story; a memorable encounter with God in a train which, unfortunately, has to be forgotten; a dreamlike encounter with Devil in a Church as a first step on a road which doesn't lead to Hell; finally, a forbidden encounter of a dying author with one of his protagonists who brings an impossible book as a gift.
