Also Harry should we be focusing on 10.5 much? Thanks!

I think each of the Case Files reveals a little more. I would have thought 10.8 was the most revealing, and understanding it might help to make sense of the others. Harry

This encryption has one name in English and another in French. The French name refers also to a device used to sterilize instruments.

Thank you so much everyone for your (very helpful) hints!

Can anyone describe the keyword in a way which Harry will let through? Now it’s confirmed that the keyword is not related to the ford picture, the picture’s for the cipher 🙂

I also know that the keyword is quite long, but there are no hints for the keyword on case files so I was wondering whether it had anything to do with ‘the best laid plans’? Since that’s the only other clue

Thanks again for everyone’s hints! They are really helpful 🙂

If you have, wisely, collected a list of possible cribs throughout the challenges, you should be able to find the first word in the plain text and hence, by the symmetry of the encryption method, the first few characters of the key.
