Mind Reading

This spell, sometimes incorrectly called ESP, permits the caster to hear (and possibly see, if the target visualizes anything) the surface thoughts of one or more living creatures within range. The caster must designate a direction or select a visible target, and then concentrate for a turn in order to "hear" the thoughts. Each turn the caster may choose to "listen" in a different direction. The caster may stop listening, then resume again later, so long as the duration has not expired. The target creature is not normally aware of being spied upon in this way, though any creature already under the effect of this spell or any similar form of telepathy will instantly know and be able to sense the direction of the caster. Rock more than 2 inches thick or even a very thin covering of lead or gold will block the spell. All undead creatures are immune to this effect, as are mindless creatures and constructs such as golems.
