Ben took a mussed-up envelope from the hand of his chum. It was directed in crooked, printed letters: “mister tom barns.”

“Sort of blood-curdling, eh, Ben?” mused Tom.

Like all country communities, Rockley Cove had some undesirables. Over the village line, in fact, between it and the residence of the Morgans, was a little community of fishermen whose social condition was not very high.

One particular family with numerous branches was quite notorious. The name was Barber, and the younger members of the family constituted an uncouth and troublesome set. They and some neighboring lads formed what they called a secret society called the “Black Caps.” They soon became the terror of adjoining communities.
