Reading Russian literature - without a book - in solitary confinement, speaking with someone else's voice and the need to be embraced. Josie Long delves into wordless communication.

From the melody of your speech to the brush of skin on skin, Josie explores body language. We hear about secret codes sent through walls, a sudden bodily change which left a woman feeling like a stranger to herself and the importance of touch.
