Lucy put the lantern on the bench and got her first real look at the room. It was smaller than she'd thought. There was no window. It had been bricked in a long time ago. Dust and cobwebs were everywhere. There were mouse droppings along the wall.
Lucy closed her eyes, tried to blot it all out.
She looked at the doorknob. It too was caked with dust. She picked up an old rag, cleaned it off. It was an old-fashioned white porcelain knob, set into a cast-metal plate. She felt along the neck behind the knob, and found the set screw. She angled the screwdriver behind the knob found the slot, gently turned. A few seconds later the set screw fell out. She carefully pulled off the knob, holding the spindle tightly. She didn't need the knob on the other side falling to the floor and making a racket. Then she went to work removing the plate. Four screws. Although she could not see that well, it looked like the screws in the plate were nearly stripped. She'd have one chance to get them out.
She looked at the head on the screwdriver, which was also rounded, dull with age and use. She put the screwdriver into the slot, put all of her weight behind it, doing her best to keep the tool perpendicular to the door.
She took a deep breath and tried to turn it. Nothing. She backed off, tried again. This time she felt purchase.
The screw turned. Not much, but it turned. Yes, Lucy thought.
A lock was just a device with moving parts, right? If there were moving parts, Lucy Doucette could handle it.
She set about her task.
