A few years ago, in a prison in England, Albert Michael Wensbourgh, a very violent prisoner, suddenly became a man of extreme kindness. What took place to operate such a personality change? Questioned, Wensbourgh told that an angel was the architect of this transformation, and when the psychiatrists and specialists studied the case, could not find any kind of imbalance in his mind. The case aroused the curiosity of many journalists, but it was the young Spanish writer Maria Vallejo-Nagera who had the opportunity to interview Wensbourgh.
