He put the roughly carved lips to his ear, while the Doctor raised the other to his own mouth.
“You can hear no murmur?” said the Doctor.

“I can give you a bed.”
“A bed? What rot! No, thank you, I’ll be comfortable enough here.”
He curled himself up and went asleep before the Doctor’s eyes.
When the Doctor entered his sitting-room the next morning the apartment was empty.
