Sukrasan's new form is not good enough to pass the penetrating eye of Pipeck.  The soothsayer informs Sukreep, who passes the word on to Phra Ram, that the battle is being observed by a spy.  Hanuman is summoned and ordered to capture him.

Now, while Peepeck with his special gifts is able to pick out the imposter immediately, Hanuman finds it much harder.  He flies round the battlefield for some time, but gets so confused by the ceaseless movement of the monkeys that he gives a great howl, bringing them all to a standstill, and at that moment transforms himself into a mountain encircling the entire army.

"Now then," he says, "you will pass through my hands, one by one, until I find the demon.  And when I find him . . ." and here he utters threats so horrifying that Sukrasan can hardly control his trembling limbs.  He wishes most heartily he could find a way of escaping, but as there seems no choice but to pass through Hanuman's hands, he joins the waiting line of monkeys and trusts that his appearance is sufficiently convincing to pass muster.  However, at the moment when it is his turn to be lifted up and sniffed at and examined closely by the Son of the Wind, Sukrasan is so terrified that he inadvertently changes back into his original form, and the game is up.
