For a terrifying moment Paul could not feel her breathing.
For a terrifying moment she passed directly in front of him.
Then, at the most terrifying moment, the lights came on.
It was, without question, the most terrifying moment of his life.
For a terrifying moment the man thought she might be coming to see Robert.
It is the biggest, most terrifying moment of his life.
For one terrifying moment, he could not move his fingers.
It had been the most terrifying moment of his life.
The terrifying moment seemed to last for ever, but it can only have been a split second.
For a single terrifying moment I thought he was going to hit me.
