Mr. Catesby eyed her in perplexity, and was about to address another
tender remark to her when she was overcome by a slight fit of coughing.
At the same moment he started at the sound of a shuffling footstep in the
passage. Somebody tapped at the door.

"Yes?" said Prudence.

"Can't find the knife-powder, miss," said a harsh voice. The door was
pushed open and disclosed a tall, bony woman of about forty. Her red
arms were bare to the elbow, and she betrayed several evidences of a long
and arduous day's charing.

"It's in the cupboard," said Prudence. "Why, what's the matter, Mrs.
Porter?"

Mrs. Porter made no reply. Her mouth was wide open and she was gazing
with starting eyeballs at Mr. Catesby.

"Joe!" she said, in a hoarse whisper. "Joe!"

Mr. Catesby gazed at her in chilling silence. Miss Truefitt, with an air
of great surprise, glanced from one to the other.

"Joe!" said Mrs. Porter again. "Ain't you goin' to speak to me?"

Mr. Catesby continued to gaze at her in speechless astonishment. She
skipped clumsily round the table and stood before him with her hands
clasped.

"Where 'ave you been all this long time?" she demanded, in a higher key.
