I was wrong.

A postscript now that I've had time to think is that it's not possible to construct such a Sudoku. Well, the question itself is logically flawed.

I've stated that the puzzle must have a unique solution. But before you make the move and write in the number 1 in the particular location above, the puzzle (by definition thanks to the question) has multiple solutions.

Hence the question is flawed itself, and I am stupid.

Oops.

Dealing with the after life

-
My father died recently. That was the reason for all of the train trips up and down to Chester which you may have noticed. This posting isn't about that, though, it's about what happens after life. Not the grieving process, or deciding which ornaments to keep for sentimental reasons - but the logistical process of administering an estate. It's both a simple process, and a complex one. I've never sent to many letters or written so many cheques in such a short space of time. Out of the process of sorting out my Dad's estate, one thing has stood out for me. That is the difference in level of service - and general approach to the situation - taken by different companies. The requirements have been the same in every case. In every single case, I just want the company to stop providing whatever service they have been providing, and tell me whether the estate owes them money, or they owe money to the estate. Simple. Or so you'd think. I think it's worth a

A war of words

-
Almost every morning I walk through Paddington station on my way to work. There's a little booth where they sell smoothies made with fresh fruit which are rather nice, and a good way to start the working day. I order my smoothie, and as it's being made, I pay. Whenever I pay, the staff ask "would you like a pastry with that?" I don't want a pastry with my smoothie and say "no thank you". But that got me to thinking - is there a way in which I could ask for my smoothie in such a way that I won't get asked if I want a pastry at all. Saying "I would like a mango smoothie but I don't want a pastry" is a little direct and maybe a little rude. I've tried "I would just like a smoothie". I've tried "I would like just a smoothie". I've tried "I'd just like a smoothie today please". And I always get asked if I would like a pastry. So - I give up - I cannot think of a way to ask for my smoothie w

A book I didn’t like

-
I read a lot of books.  Not as many as I’d like to – but that’s mostly because of my high ambition level when it comes to reading lots of books rather than a lack of reading. Sometimes I read books which teach me things, and sometimes I read books which make me think.  But sometimes I just like to read a good story.  No messages, no agenda, just a good story. One of my favourite books is “Haunted” by James Herbert.  It doesn’t pretend to preach any message, nor to stimulate any intellectual debate.  It’s just a great ghost story. However, I’ve found other James Herbert’s books disappointing.  The sequel to “Haunted” – which is so forgettable that I’ve forgotten its name – was terrible.  As was “The Secret of Crickley Hall” which I just finished reading. I’ve literally taken this book around the world with me.  I’ve carted it in my suitcase to provide reading on a long-haul flight home many times, and never started reading it.  Until the middle of last week, that is.  One evenin
