There are only two door keys among them all." He took the keys and led the way towards the door hidden behind the grove of nut-trees.

The nightingales were singing as he passed beneath the boughs, followed by Sor Teresa.

Juanita hurrying up towards the house by another path, turned and glanced anxiously over her shoulder.
"This, I think, will be the key," said Mon, affably, as he stooped to examine the lock.

And he was right.
He opened the door, passed out and turned to salute Sor Teresa before he closed it gently, in her face.
"Go with God, my sister," he said, bowing with a raised hat and ceremonious smile.
He waited until he heard Sor Teresa lock the door from within.

Then he turned to examine the ground in the little lane that skirts the convent wall.
