So please don't disparage the idea of someone in their 30s getting a kick out of Melling's goblins. If you buy it for your littl'uns – and buy it you should – I dare you not to smirk copiously when you turn to it yourself. It's a guilt-free little joy for all the ages. And I rather think you'll need to buy the others, too – they're all perfectly self-contained, but completing the set on this occasion is a must.
