He scrambled down it in time to hear the key turn again, but the jug of water stood inside.

He took it up and drank a deep draught.
He had not known that he was so thirsty, never dreamed that water could be so appetising.

He heard Tinker summon his men, and when he came back to the top of the tower, he was riding away.

He watched him go with a sinking heart, and, since he was so empty, it had a good depth to sink to.

Twice he opened his mouth to call him back, but greed prevailed.
The day wore wearily through.
