Difference Between Wargrave And Armstrong

Wargrave and Armstrong both have motive because they were both suspected by Louisa. Louisa convinced the rest of the guests how they had the most access. Because of Louisa everyone realized she was right. Armstrong was the only doctor on Soldier Island so there was nobody there to corroborate what he was saying or administering. Louisa also believed Wargrave had motive because he was sort of the leader of the group and everybody did what he said. This victim died due to injection of Potassium Cyanide. She had an increase of white blood cells count and a flood of adrenaline in the body due to fear. This victim knew she was going to die, but tried to fight the attacker. She failed, causing her to die.
