Hi Brendan
You are right, but these are given a title, in this case 'Swedish Sherlock, which almost always relates closely to the answer.
So sometimes you can work them out 'backwards' from that if all else fails.
Anyway I have finally come up with the answer, HANKELL, which fits, but looking that up cant really find what or who Hankell
is / was.
Thanks for your reply. Now onward to my next puzzle. Some of these can be difficult but dont like to be beaten.
