A man in the costume of a monk, who had followed her across the room, touched her on the shoulder.

He spoke in a quiet, unfamiliar voice with a foreign accent, "You are Lady Maggie Trent ?" "Yes!" "Will you please go to box number fourteen, on the second tier?
There is some one there who waits for you." "Who is it ?" she asked.
The monk had glided away.

Maggie, after a few minutes' reflection, slipped out into the corridor, mounted one flight of stairs, and passed along the semicircular balcony.

The door of box number fourteen was ajar.

She pushed it gently open and glanced in.
