Dear Jazzgirl & Scorpiojo
Ah, I see. I had MIGRANT for VAGRANT - just picked the wrong state, really & yes, I should have spotted that AEGIS was a mix of SEA & GI.
(I'm assuming that, somewhere, there is a well-known dog called "Shadow" though only too obviously it's not w-k to me. Why can't the setters stick with "Bellman"?)
Thank to both of you for your invaluable assistance which has enabled me to spot 29A & so finish.
