It was such a pleasure to deliver my raven to the Tower of London the other day. The sun was shining, the buildings were all dressed up for Christmas, and the incredible atmosphere that envelops you as you drive into such a historic site was a unique experience in itself. I was then greeted with the warmest of welcomes by Clive, the Chief Gaoler, followed closely by José, the Tower’s team leader and host, who had helped to organise the day.
