"Who Killed Lucy Lane?"
Lois Lane learns that her sister Lucy has apparently died in a canoeing accident in South America. She uncovers a diary of Lucy's that reveals that her sister was a member of the 100, who are also looking for a scientist with the plans for a super-bomb which can destroy a continent. Both Lois and Superman go on the trail of the 100 and protect the scientist from the organization. After the case is closed, Lois refuses to go back to Metropolis with Superman, still needing time to get over her sister's apparent death.
