Detect Truths. 2/day Water horse can cast Detect Truths. For the duration (1m), Water Horse can detect when someone tells the truth or when they attempt to lie and can relay this information to their bonded player. Note you do not need to understand the language being spoken to know if it is a truth or lie but may not understand the context of that information unless another party member understands what is being said.

Questions verbally directed at the target creature naturally shape the course of its thoughts, so this spell is particularly effective as part of an interrogation.
