Ghost story, Westminster Abbey, twins...?

Identical boy twins, I think. One called Seamus or possibly Hamish?

I've been trying to remember the title for years.

Now have respectable excuse to bug people about it as writing a scheme of work based on children & ghosts!

Is this it?

[ravenAK]

It is!

Brilliant.

Thanks bruffin.
