Before I begin trying to fathom the meaning of the thematics, I'm still unsure about what I think is one.
Suspicion of Otis lifts failing to open (5)
My answer, which is a cockney pronunciation of a group of 4 legged animals, is parsed "suspision of Otis" followed by a 5 letter musical term for "lifts" (also a slang term for part of the anatomy) minus its first letter/'failing to open'.
The problem is )t doesn't seem to be in any dictionary - have I got it wrong?
