17a The second busiest port in France *L *A*R* At first glance, clue seems obvious but answer to 18 across which I believe ends in L throws a spanner in the works. Or just compiler error?
The criteria is:
1. No planes overhead
2. Not near any towns or cities
3. No rowdiness or crime hotspot
4. Away from any motorways or trunk roads
The nearest village would be sufficient?...
