The greatest book ever written. Professor Reginald Tyler's The True History of Planets was a twentieth-century classic; an epic of dwarves and swords and wizardry. And definitely no poodles. Or at least there weren't when the Doctor read it. Now it tells the true tale of how the Queen of the poodles was overthrown; it’s been made into a hit movie, and it’s going to cause a bloodbath on the Dog World — unless the Doctor, Fitz and Anji (and assorted friends) can sort it all out.
