At the corner of the two passages stood a table with a lamp and some candlesticks.

This time Wogan took a candle, and lighting it at the lamp turned into the short passage.

It was dark but for the light of Wogan's candle, and at the end of it facing him were two doors side by side.
Both doors were closed, and of these the one on the left gave onto his room.
Wogan had walked perhaps halfway from the corner to his door before he stopped.

He stopped suddenly and held his breath.

Then he shaded his candle with the palm of his hand and looked forward.
