The five I choose are ALL original (black covers) Target Novels.
1) Masque of Mandragora
2) Talons of Weng-Chiang
3) The Loch Ness Monster
4) Android Invasion
5) Revenge of the Cybermen
And what I like most about that one target novel ["The Dinosaur Invasion"] (though there might have even been 'moore' of them, but I can only think of the one, right at this moment) is that while the televised story was Jon's the book put Tom there.
Name Five of Tom's relatives. [HINT: see photo section.]
