the carved stones where they too discover the clue to the second part of the task. With a time advantage, Saskia and Adrian arrive at Coricancha to find a replica golden disc (representing Inti) hanging from a circle of candles. Saskia attempts to melt the disc before realising that the clue is on the paper found in Cusco which depicted an archway above the name of Coricancha. Together with Adrian they begin their search of the site for an arch which matches the picture. When they find the arch, the room beyond it contains another paper clue with a picture of the golden disc and a word written in invisible ink. After some debate they realise this has to be returned to the candles and heated to allow the acid in the smoke to reveal the message. Meanwhile, upon seeing what Saskia is doing, Simon and Mairianne decide to copy her quickly, but in their haste allow their parchment to catch fire. Saskia's patience of slow heating pays off, revealing the next location (Wanuska Wasi). In the next location (an Inca tomb complex), the teams have to follow a puma symbol through the network of caves before finding a wall with a code on it. Jamie had previously told them to "break the code", and in a pun, the contestants do not need to decipher the code, simply break the wall down with brute force. Saskia and Adrian solve this first and find a llama foetus wrapped in a cloth used as a shaman offering. Mairianne also solves the 'break' pun and, upon finding the shaman offering, appears to solve the message on the cloth ahead of Saskia. Despite this, it is Saskia and Adrian who have the lead in this challenge as they begin a rafting trip toward Ollantaytambo. Saskia and Adrian are physically disadvantaged in this task and Simon and Mairianne close the gap only to find the random current in the rapids slows them down. Andreas Holland explains the significance of Aguas Calientes as the teams solve a pigpen cipher, outlined in the shape of an ankh. With Adrian slowing Saskia down, Simon and Marianne arrive at the clue first and methodically work through the code to solve it before Saskia has a chance to decipher it. Before the final challenge, the teams eat guinea pig with local families and spend the night there. The next day
