The Master’s Dalek Plan is definitely one of the all-time greats!
A lot of my favorite titles are novel titles, a lot of them are very strange and evocative, drawing you in to wonder what they could possibly mean, others are humorous/fun or just clever.
A list of some I particularly like:
The Highest Science, The Dimension Riders, The Left-Handed Hummingbird, Strange England, The Crystal Bucephalus, Infinite Requiem, Dancing the Code, Sky Pirates!, Invasion of the Cat-People, The Also People, Christmas on a Rational Planet, Return of the Living Dad, The Devil Goblins from Neptune, Alien Bodies, Vanderdeken’s Children, Last Man Running, The Face-Eater, The Banquo Legacy, The Quantum Archangel, Eater of Wasps, The Year of Intelligent Tigers, The Slow Empire, Psi-ence Fiction, Dying in the Sun, The Book of the Still, The Infinity Race, Reckless Engineering, Emotional Chemistry, Sometime Never…, The Eleventh Tiger, The Sleep of Reason, The Algebra of Ice, To the Slaughter (this last one I can’t not hear David Tennant as the Doctor saying in my head every time I think about it)
