She lit her candle; and it was the light of the candle which awoke her maid.

The tent was a double one; the maid slept in the smaller portion of it and a canvas doorway gave entrance into her mistress' room.

Over this doorway hung the usual screen of green matting.

But place a light behind them and they become transparent.

This was what Violet Oliver had done.
She had lit her candle and at once a part of the interior of her tent was visible to her maid as she lay in bed.
The maid saw the table and the sealed parcel upon it.
