Thank you Ana for the explanation!
I think we should have a Hoodie Hoo day over here in the UK as well (but the weather is so unpredictable you couldn't decide what day it should have been until the spring!
) It was certainly one today brrrr! (but I'm thankful that we don't get the lowest temperatures that you get in some of the places in the US)- as for cabin fever - if you can also get it from being out & about everyday - I've definitely got it!!
I'd better have a guess now - it's sounds like it should be a Sherlock Holmes? - Mystery of the Mummy?
