What shocking news does Beah receive while staying at Khalilou's house in Mattru Jong?

One messenger arrives with all of his fingers except for his thumbs cut off - a mutilation called "one love" by the rebels in mockery of the Sierra Leonean custom of raising a thumb and saying "one love" in imitation of reggae music culture. This same messenger has the initials RUF carved into his body to mark him as belonging to the rebels (the "Revolutionary United Front").
