Bartimaeus leapt up onto a roof. His words echoed in my mind. 'Some pumped up imp.'

I curled up in a ball. Bartimaeus looked back at me, and waved. Slowly. Just like he had in Prague when our master was killed.

We would never forget Prague. The secret looks we had given each other, holding hands, saving each other from afrits, and teasing the imps.

When I found out we would be working together I had hoped it would happen again.

It didn't.

A roll of thunder shook me from my thoughts. I smelt earth.

I shuddered. Golems.

Then I smiled. Prague. Bartimaeus.

I trotted down the road after the thunder.

The darkness closed in on me. I sent a flare up and backed into an alley on Gibbet Street. I heard Bartimaeus yell my name. I sent up another flare and screamed as the darkness closed in on me.

I whispered one word. "Bartimaeus."

I will never forget you.
