Thanks Tookie. I had put 'emigrated' for 23a - that's where my mistakes had come from. So, going with agate and extreme I've got e-i-r-e-a for 23a. What can it be?
Wonder if the quick job in church might be living. A job is what you do for a living, and churches tend to talk about the quick and the dead. So living would be quick in this instance (Perhaps).
