I must admit it was a double challenge for myself: a mistery and the language...
While I can easly read a regular fiction books in my non native language - english, I found it to be rather difficult in case of the contest's What The Butler Saw text... Too many clues were unclear, too many of the "clues" are possible just funny inserts so those confused me even more than a storyline...
Anyway, I just gave my best guess yet I have the feeling I am wrong with that and I will regret the time spent for "solving" the mistery since I believe I missed or misunderstood many things there...
So a request from mine

Next time, use simpler english and more complex story
