Hello, Elle!
John B. is an Irish author, well known for short stories.
I like him.
I first heard of him many years ago.
I watched a film called "The Field", starring Richard Harris and John Hurt, and it was taken from a John B. Keane book.
And I found out a little bit about him (no laptop in those days!) and liked his stuff.
4a, Baggage can be an "albatross" around your neck.
Scotland is "Alba", "s" for southern, type is "sort", reversed onto Alba.
14, was a new meaning to me.
The man is "Martin", "g" for good, and "ale" for drink.
"Martingale" is a system of betting in which you double your stake every time you lose.
5, The horror is a "brat", lives is "is", with "lava" which may be "magma".
"Bratislava" is the city.
How's that ?
