Rowan, he isn’t unwell. He’s actually a public figure, very well known in his field, and highly respected. He’s also an authority on Ancient Britain and Scandinavian folk law, and a man of great curiosity, so he was experimenting to see if it worked – or so he says. This tale, which was shared by his wife around my dinner table, caused great hilarity among that particular group of friends, all of whom are very practical and down to earth. He’s a man of little humour and is not accustomed to being ribbed about anything – but ribbed he well and truly was that night. Fortunately he took in it on the chin and we are all still friends. Much to his wife’s delight, he’s given the occult a miss since then.
