"I sense the vicious doctrine of egalitarianism."

Not our words, the words of financially-motivated, fish-blooded fungus, The Collector.

One of The Sun Makers, this blob of seaweed with ideas above its station loves a healthy balance sheet and an unhealthy executionee but meets his match when the 4th Doctor, Leela and K9 visit plutocratic Pluto.

It's a miserable world of wooden tables, cardboard control panels, unappetising curries and clown's-pocket-sized credit cards.

The Doctor moos like a cow, Leela fights like a wildcat and K9 acts like a dog - much to Martin's incandescent rage.

But is the story as saleable as a tray of hot cakes or a bucket of cold sick?

Listen and find out.
