This time Will is in the deep jungles of Borneo on the quest for the most remarkable of arachnids, the Ogre-Faced Spider.
Listen as he is surrounded by moths on remote jungle plateaus, chased by Orangutans, bitten by fire ants, told local folklore of long-extinct Gigantopithecus apes, and devastated by vast tracts of palm oil plantations.
We'll go on a night walk with our second ever guest Tim Hawkes (Will's brother) who is a music teacher in Singapore, and listen to the world premier of 'Hominid', his new track.
