What happens
Holmes and Watson read a newspaper article praising Athelney Jones's arrest of Thaddeus Sholto and others. Holmes summons the Baker Street Irregulars, led by Wiggins, to search for the steam launch Aurora and its owner Mordecai Smith. Watson reflects on his personal stake in recovering the treasure for Miss Morstan. Holmes deduces that the mysterious assailant is a native of the Andaman Islands based on footprints and weaponry.
