NAIROBI, KENYA: It is a truism of self-respecting murder mysteries that in the aftermath of a murder everyone has something to hide. Agatha Christie, supreme writer of murder mysteries, dramatised this in The Murder of Roger Ackroyd, where the Belgian detective Hercule Poirot sits all the potential suspects in a room and declares, “Every one of you in this room is concealing something from me. It may be something unimportant – trivial – which is supposed to have no bearing on the case, but there it is. Each one of you has something to hide.”
