Under the ladder to the loft a door led to a woodshed at the end of the stable.
As she went up the ladder she heard somebody moving in the shed.
"Who's that?" she asked sharply.
There was no answer.
She descended and tried the door.
It was locked.
"That's all right, Boy," called a quiet voice. "It's only me."
"Mr. Silver," she cried. "What on earth are you up to?"
"After a rat."
"A queer time to choose."
