Message

You whisper a message. The target hears the
message and can reply in a whisper that only you
can hear. You can cast this spell through solid
objects if you are familiar with the target and
know it is beyond the barrier.
Magical silence, 1 foot of stone, 1 inch of
common metal, a thin sheet of lead, or 3 feet of
wood blocks the spell. The spell doesn't have to
follow a straight line and can travel freely around
corners or through openings.
