The amplifier was shaped like a small metal box with conical horns projecting from five of the six faces and a pattern of depressions and bumps on the sixth face which acted as control switches. The device was capable of projecting and baffling recorded and live sound and a variety of other sophisticated sonic functions of which she was wholly ignorant. It fitted comfortably in Ketha's hand and it felt slightly warm to the touch on this winter morning. The next thing was to smuggle it to Klane in his glass prison without the creature's knowledge. She already had a plan for that.
