Why detective video games are the perfect way to experience a mystery

In one of her best books, The Murder of Roger Ackroyd, Agatha Christie puts these words into the mouth of her least favourite character, Hercule Poirot: "Understand this, I mean to arrive at the truth. The truth, however ugly in itself, is always curious and beautiful to seekers after it." All detective stories are an attempt to reflect this. Uncovering the truth through clever reasoning, observation and logic is wondrous. You are forced to look at the world anew: a misplaced chair is no longer just a chair, but indicative of a killer's escape; a removed lightbulb tells us the killer did not want to be seen.
