I'm still struggling to find a good answer for this. Already have Glossy Coat but I don't think that's right.
Also "On the Medway". ?

How many letters for the Medway clue? Will it be the name of a location on the River Medway?

No number for letters. Two words. first begins with G second with C. I have put two names of towns on the Medway but I'm sure there must be more to it than that!
