Part one of The Visitation aired exactly thirty years ago today. The Target novelisation (title #69 in the range) was published later in 1982. Not only was the book the first Target title that I bought, it's also the very first item of Doctor Who mrechandise in my ever expanding collection.
Many hundreds of pounds later, I still love this story, one of Peter Davison's finest, and cherish my dog-eared book. Richard Mace (Michael Robbins) makes a great (though cowardly) highwayman-cum-companion, and the Terileptil baddies really deserve a rematch with the Doctor, even if it's just for destroying the sonic screwdriver!
