The tunnel isn't through to the end yet, I'm sure of it.

If it were, they'd have taken in the TNT, for it must be ticklish work keeping it hidden elsewhere, with scores of Sikhs watching day and night.

But they're very near the end of the tunnel, or they wouldn't be opening up that fruit stand.

You'll hear them break through.

When you're absolutely sure of that, come out of the mosque and say Atcha--just that one word--to the Sikh sentry you'll see standing under the archway through which we'll enter the courtyard presently.
