If I rang twice, he was to show the gentleman out.

If I rang once, he was to keep out of the way, and follow the gentleman whereever he went till he got back to the inn.

Those were the only preparations I could make to begin with; being obliged to wait, and let myself be guided by what turned up.
About a quarter to seven my gentleman came.

But far away the ugliest and dirtiest blackguard I ever saw in my life was Mr.Alfred Davager.

He had greasy white hair and a mottled face.
