How do I open the doors in the toadstools?

1. You don't; something else does.
2. Watch a toadstool for a while; just WAIT around.
3. The door opens when the shadow is on the door.

I'm inside a toadstool but the door closed on me. How do I get out?

1. The shadow that opened the door kept moving.
2. The door closed behind you when the shadow moved on.
3. Too bad the shadow won't come around again until after the bomb explodes. You need to stop the shadow on the door.

How can I stop the shadow?

1. Have you been to the vertex?
2. There's a gnomon missing from the sundial.
3. If you screw the gnomon from Kensington Gardens into the hole, a lever will appear. Easier said than done.
4. Aristotle said he could lift the world with a long-enough lever. You can stop the world with your lever.
5. The shadow stops moving when the lever is lowered. Or is it the sun that stops?

My threads clash. What do I do?

1. Get a better tailor.
2. Seriously, you need to reverse one set of threads.
3. Look around and see if you can make things reverse.
4. The writing on the sculpture in the Arboretum will reverse.
5. To do this, walk completely through the pergola. N.U.S.D.
6. This switches the handedness of everything outside the pergola.
7. If you carry the gnomon with you, it won't switch, and the hole at the vertex will, allowing you to screw the gnomon into the hole.
8. This will probably mess up your map, but you can fix that by going through the pergola without the gnomon.

How do I get the shadow to stop on the toadstools?

1. If you don't know how to stop the shadow, look two questions earlier.
2. There is an easy way and a hard way.
3. The hard way is to lower the lever as the shadow moves across a symbol.
4. The easy way is to use the ring. Lower the lever, stopping the shadow, then turn the ring (and the sun along with it) so that the arrow on it points to where you want the shadow to stop.
