k and that's all. Now take this crazy woman--Mary Randall--"

While he spoke he had opened a letter containing a second enclosure. It
was an envelope of a peculiar shape and its color was dark blue.

CHAPTER XIII

THE READER MEETS ANOTHER OLD ACQUAINTANCE

The sight of the blue envelope had transfixed Grogan. He stood staring at
it like a man in the presence of a ghost.

"The blue envelope, again," he cried. "A harpoon for you, John."

John Boland made no reply. He reached for his paper knife, ripped open
the envelope and drew forth a sheet of blue note paper. He read with a
gathering frown what had been written on it. Then he reread it, muttering
under his breath.

"Does it hurt you much, John?" inquired Grogan, enjoying the other's
discomfiture.

For answer the elder Boland scrutinized Grogan over his glasses.

"What do you know about this, Mike?" he demanded.

Harry returned no direct reply. Opening his note he read:

"'We count on young men like you, Harry Boland, to lead the fight we are
making to save our Little Lost Sisters. Mary Randall.'"

"Now," chuckled Grogan, "you know how I felt when I got my little blue
envelope this morning." As he spoke he tore off the end of the envelope
which he had held unnoticed. Inserting his finger and thumb into the
envelope he went on:

"Do you know, I never did like the color of blue--"

He broke off as he lowered his eyes to the enclosure he had brought out.
It was another blue letter. Grogan started up and jerked out the note.
Holding it at arms' distance he read:

"'The strength of Ireland is in the purity of h
