Take the following as truth: In 1846, during the course of an unsavory palace intrigue involving an unsolved murder, meddling by the queen, and the massacre of some 100 high-ranking court figures who had been lured to a palace courtyard, the instigator of these events became the power behind the throne.
Then the following statement: "All court figures survived the attempted massacre by convincing the assassins to spare them." is true, false, or inconclusive?
