Seconds were lost because Duke did not know how to handle its latch.

There was something else that Duke did not know.

How had the Duke known about him in the first place?

Duke and I know what it's going to be like, very soon.

Duke had always known that it would come down to this.

Obviously, the Duke had known the situation out here when he gave him the job.

The man will swiftly think that the Duke knew all along.

By heavens, the Duke shall know how slack you have been!

Smiling grimly, the Duke knew what he had to do.

No one asked how the Duke knew the enemy watchwords.
