The phone lay on the lighthouse steps, where the tide had left a necklace of weed.

It was an old black telephone, heavy enough to crack a skull. Its cord had been cut clean through.

It rang.

Mara stood above it with her morning tea cooling in her hand. There were no boats in the harbor. No footprints on the steps but hers.

It rang again.

She carried it inside and set it on the kitchen table. The bell stopped as soon as she lifted the receiver.

For a moment she heard only water: a slow, patient drip.

Then a man said, “Has the light gone out yet?”

“No.”

“Good. We still have time.”

Mara looked toward the stairs. Above her, the great lens continued its steady turning.

“Who is this?”

The man began to cry.

She recognized him before he answered.

It was her husband, and she had scattered his ashes yesterday.

There were eighty-three steps to the lantern room. Every night for nineteen years, Ellis counted them, and every night the sea tried to drown him out.

Tonight, he counted eighty-four.

He stood at the top with his hand on the rail, listening. Beneath the wind came a small, persistent ringing.

The phone sat on the windowsill: black, rotary, glistening with seawater. Its cord ended in a frayed knot. Ellis had thrown one just like it into the sea the winter his wife died, after the calls from the hospital stopped.

He let it ring seven times.

“Hello?”

For a moment, nothing. Then the familiar sound of someone warming her hands with her breath.

“Ellis,” his wife said. “Don’t count the stairs again.”

Below him, the lighthouse door slammed.

He gripped the receiver.

“Why?”

Her voice dropped so low he almost missed it.

“Because one of them is coming up.”

For locksport, practice only on locks you own or have explicit permission to pick, and use a spare practice lock—not a lock you rely on. Picking can damage a lock or leave it unreliable.

What you’ll need

• A basic pin-tumbler practice lock, preferably a cutaway model
• A tension wrench that fits the keyway
• A short-hook pick

How the lock works

Each pin stack has a lower key pin and an upper driver pin. Without the correct key, a pin crosses the boundary between the rotating plug and the housing—the shear line—and prevents rotation.

Picking means lifting each stack until the gap between its two pins reaches that line. Light rotational pressure lets you set them one at a time.

Single-pin picking, step by step

1. Insert the tension wrench.
   Put it in the top or bottom of the keyway, leaving room for your pick. Apply very light pressure in the direction the key would turn. Start lighter than you think necessary.

2. Locate the pins.
   Slide the hook into the keyway and gently feel along the pin row. Lift each pin slightly to learn its position and springiness.

3. Find a binding pin.
   While maintaining tension, test the pins individually. Most will feel springy; one may feel noticeably firmer or resistant. That’s usually the binding pin.

4. Lift it slowly.
   Raise that pin with the hook’s tip. When it reaches the shear line, you may feel a small click, a reduction in resistance, or a tiny movement of the plug. Stop lifting there.

5. Find the next binder.
   Keep the tension steady and feel through the pins again. Another pin should now bind. Repeat the process rather than expecting a fixed front-to-back order.

6. Let the plug turn.
   Once all the pins are set, the plug should rotate under the tension wrench. Don’t force it.

Common beginner problems

• Everything feels rigid: You’re probably applying too much tension. Ease off.
• Nothing seems to set: You may have too little tension, or you may be lifting the wrong pin.
• A pin goes high and the lock stops progressing: You may have overset it—pushed the key pin above the shear line. Release tension to reset and try again.
• Pins keep dropping: Your tension may be fluctuating. Aim for light, steady pressure.
• You can’t distinguish pins: Slow down and keep the pick tip under one pin at a time.

A simple practice cylinder without security pins is the best starting point. Focus on learning the difference between springy, binding, and set pins; speed comes later.

For locksport, start with a practice lock you own that isn’t installed or in use. Picking can damage a lock, and permission matters—don’t pick someone else’s without explicit authorization.

How a pin tumbler lock works

Each pin stack contains a key pin and a driver pin, pushed down by a spring. The correct key puts the gap between those pins at the shear line, allowing the central plug to turn.

Picking recreates that alignment one stack at a time. Slight turning pressure makes one pin stack “bind”; lifting it to the shear line lets it stay set while you work on the next.

What you need

• A basic, preferably non-security practice cylinder
• A short-hook pick
• A tension wrench that fits the keyway without blocking the pick
• Good lighting and a comfortable grip, or a small vise

Single-pin picking, step by step

1. Check the lock with its key.
   Make sure it operates smoothly and note which direction the plug turns. A worn or sticky lock is frustrating to learn on.

2. Place the tension wrench.
   Fit it into the top or bottom of the keyway, leaving room for the hook. Apply a very light turning force in the unlocking direction. Think gentle fingertip pressure, not twisting a screwdriver.

3. Feel the pins before trying to set them.
   Insert the hook and gently lift each key pin individually. On a conventional cylinder with the pins above the keyway, you lift upward. With no turning pressure, each pin should generally feel springy. Learn their spacing so you can distinguish one from the next.

4. Find a binding pin.
   Reapply light tension and test the stacks one at a time. Most will still move relatively easily; one will feel firmer or more resistant. That is usually the binding stack.

5. Lift the binding pin slowly.
   Raise it in small increments. When the gap between the key pin and driver pin reaches the shear line, you may feel a tiny click, a slight movement of the plug, or a sudden change in resistance. Stop lifting there. A click alone isn’t proof that a pin is correctly set.

6. Find the next binder.
   Keep the turning pressure steady and test the pins again. Manufacturing tolerances determine the binding order; it usually isn’t simply front-to-back. Work on whichever pin now binds.

7. Repeat until the plug turns.
   Once every driver pin is clear of the shear line, the plug should rotate under the light pressure already on the wrench. Don’t force it.

Common beginner problems

• All pins feel rigid: You’re probably using too much tension. Ease off.
• Pins move, but none seem to set: You may need slightly more tension, or you may be missing the binding pin.
• Progress stops after a click: You may have overset a pin—lifted its key pin into the shear line. Release tension, let everything reset, and try again.
• The pick won’t move freely: The wrench may be crowding the keyway, or the pick may be too large.
• You’re getting nowhere: Pause and reset rather than applying more force.

The main skill is tension control, not pushing hard with the pick. A cutaway lock helps you understand the mechanism; a repinnable practice cylinder with only two or three pin stacks is especially useful for learning the feel before moving up to a full lock.
