Well, slap me with a wet haddock! Today there turned up in the Royal Welsh Mail one tube containing a very interesting and colourful map of shipwreck sites off the mouth of the Columbia River, US of A. I have no idea who sent it, the only return address is a bookshop in St Helens, Oregon - and the signature on the customs declaration is a masterpiece of illegibility, but whoever you are, thank you very much indeed. I don't even know if you are my original designated Santa or a late "stand-in" (the parcel was posted 23 January), but either way, the gesture is much appreciated.

Thanks a load.

Andrew
