There are a large number of queries I have (I have only done just over half of the answers at this stage) , but I wonder whether I am on the right track with the following.
11A Is the key INS?
13A Why is bearskin OF, or isn't it?
22A What should I be looking for with the six initial letters I have? I suppose I need one letter, followed by a two-digit number ...
And yes, Hamish is unambiguous ... just tortuous!
Thanks
