An idea just flashed through my mind.

I just got an idea.

It makes me shiver just to think of it.

I have one thought in mind.

I hit on an idea.

One thought, and one only, pursued her remorselessly in different forms.

The thought makes me shudder.

But at that moment, standing on the empty platform, a single thought crossed my mind.

Yes, that was the thought which would solve everything.

They're nothing but a tie...'

There is only one truth.

But I remember one thing I'd read in that book is, every evening in China town

There was only one problem.

There's only one problem.

There's just one problem.

There is only one pillow.

There's only one bullet left.

There's only one door.

There's only one difficulty.

I only need one.

There's only one clean cup.

There is only one book on the desk.

There exists only one possibility now.

I only need one thing.

I only have one sister.

I only have one so far.

Tom only has one arm.

Tom has only one leg.

Tom has only one squirrel.

I have only one sister.

I have only one pen.

You only get one life.

Tom only has one leg.

We have only one objective.

There's only one clean cup.

Change alone is eternal, perpetual, immortal.

Tom had only one leg.

I only have one so far.

Tom's house has only one bedroom.

There's only one problem with our plan.

There's only one bottle of red wine left.

There's only one road on the island.

I only have one friend left.

I've only had one girlfriend.

At present the same thought filled both their minds and dominated all else Nicholas's illness and approaching death.
