Chapter One
The Corridor
The station appeared on the second morning of the crossing, and Efa Jones, who had seen its photographs for years, discovered that the photographs had all missed the point.
The point was the scale, and the scale was double. Meridian Station itself was small: a working platform the size of a village square, stacked with sheds and tanks and one radar ball gone matte with salt, standing on its four legs in the middle of an ocean that went to the horizon in every direction and then went on. From the supply boat's rail it looked like the last house of a drowned street. That was the first scale.
The second scale hung beneath it, invisible, and it was the reason everything else existed: the array. Two thousand metres down, at the depth where the sea arranges its secret corridor, the station's hydrophones hung in the dark on their moorings and listened, as they had listened without one hour's interruption for fifty years, to the deep sound channel, the ocean's own long distance line, in which, Efa knew as a matter of physics and was about to learn as a matter of the heart, nothing that speaks is ever entirely lost.
Dr. Osei Mensah met her at the crane basket, sixty three years old, grey bearded, in a jumper that had clearly survived decades of this exact wind, and his handshake was a formality but his first question was not.
