6 DOWN Pericles
P (Quiet) Eric (Boy) Les (The French) = PERICLES, Prince of Tyre (Shakepeare play)
Not sure where the 'gradualism' bit comes in.
11 ACROSS Skeptic
Moore, a philosopher, wrote on Scepticism
The US spelling is sKeptic, so I'm assuming this is where the Missouri comes in
Confirmation would be appreciated.
NOW TO MY OWN PUZZLEMENT...
13 ACROSS They had a dream in Edgar's piece
I have TE_N_ (5) The only real solution is TERNS - do these birds have a dream in something by Poe - excuse my ignorance, but confirmation would be appreciated.
Thanks in advance.
