I have Ali Higg's seal here, and I write all his letters." I did not answer, but Narayan Singh checked his camel a stride or two to make a signal to me behind her back.
"Hah!" he remarked with an air of triumph.

And I took that to mean that in his judgment Jimgrim could find use for Ali Higg's seal.
But of course she heard him, and she took it to mean that she had guessed rightly.

She turned to Narayan Singh; and because in that land, as an almost invariable rule, no business with a chief can be accomplished without bribing his minions, she worked off a little spite and offered largesse with the same hand.
"Arrange good terms for me and you shall have Ayisha." "But I have her," said Narayan Singh with a great laugh.
"Maybe.

But you haven't settled yet with Ali Higg.

Arrange good terms for my ransom, and I will see that Ali Higg wipes off Ayisha's score." "We shall see about that; we shall see," he answered.
"Yes, yes! You go and see! Go to him now!" "When we halt," the Sikh answered.
"In an hour it may be too late," she insisted.
