East Rock Lamp

The lamp on East Rock has been dark for seven nights. A silent lamp is only a rock, and a rock opens hulls. Beyond the sandbar, the supply boat waits. It answers one code and nothing else: short, then long.

The keeper, Maren, is gone. She left a log and a cold lamp. You are the next pair of hands.

FIVE BOOKS, 35 HAND-MADE PUZZLES

• Book I · Blind Glass: read what is wrong with the lamp and work the tray. Gloves before a hot chimney, water before salt, graphite on a dry axle. Order matters.
• Book II · The Boat's Mouth: hold the rotating shutter and release inside the brass marks. Learn the short, the long, and the false mark with no letter.
• Book III · Lights That Belong: seven nights, seven seas. Find the lights that belong to people. Stars, reflections, rocks, fireworks and lightning are not signals.
• Book IV · Build the Mouth: seat the lenses, set the wick, turn the cam to the boat's code, and face the heavy foot into the weather.
• Book V · The Channel: six watches on one lamp and one sea. Tend the lamp, send the code and keep the watch before the tide runs out.

A LAMP THAT REMEMBERS Oil, heat and soot sit in brass windows on the lamp base. Overfill the lamp and the glass runs hot. Hot glass splits a long flash into two shorts. Let soot build and you cannot see the sea. Every choice you make in one book follows you into the next.

THREE TIDES Slack tide shows the way after a pause. Flood tide takes no hints. Spring tide narrows the window and adds a second trap.

THREE ENDINGS First flash, True light or Late light. How well you kept the beam decides how the boat answers.

YOUR OWN SKY Set a sky plate behind the lamp glass with your camera or a photo, and print your finished night log to your photo library. Both are optional. Every puzzle can be finished without them.
