Philip briefly returns to his brother Larry from the Army, with a story about needing to head to Ireland, but instead stays in a hotel, where tragedy awaits.

Larry is convinced his brother's death wasn't suicide, and, with another close death, takes matters into his own hands.

Larry is questioned by Hyde as his prints are found on the knife. Larry and Ruth visit a nightclub and find a familiar looking couple.

Larry is placed in real danger, as efforts to get hold of the key he'd copied are stepped up.
