“He must have gone mad.”

“No; only towards Mr Saul Harrington, I’m afraid.”

They hurried back to the drawing-room, to become conscious of a hoarse, panting sound, and a low angry muttering from the couch, where the two old men were feebly struggling with Saul Harrington.

“Quick! Help here!” said the old lawyer.

George Harrington sprang to them, and pinned Saul down to the couch, from which he vainly struggled to rise.

“You had better go, ladies,” cried the young man.

“Can I be of any use?” said Gertrude calmly. “Doctor Lawrence knows how I can help.”

“Yes, help me,” said the old man. “Can you hold him?”

“Oh, yes; I have him fast for the present.”

Doctor Lawrence hurried to a table, took out his pocket-book, and wrote a prescription, tore out the pencilled leaf, and gave it to Gertrude.
