I was his only line of information: anything else would have been dangerous.

But those two were, for the moment, the only line of defense.

During this incident, Hall spoke her only line on the show.

By this time next week, it's probably the only line from today's exchanges that anyone will remember.

The only remaining line was closed on 1 January 2006.

Forget the dog under the bed, my only line of defense was a chair leg.

The only safe line of action was to walk both ways.

Which was, Tyson thought, the only absolutely true line in the letter.

It even indicated the only possible line of treatment to be taken.

It is currently the only line on the system but new lines are also under construction.
