Malicia and Keith, after freeing themselves, trick the rat catchers into admitting their crimes. The rat catchers have created a powerful rat king named Spider, which is the source of the mysterious voice that has been plaguing the rats and Maurice. Using its mental control over the rat catchers, Spider plans to wage war on the humans that created it. It sends the rats it controls to attack Maurice, Peaches, and Dangerous Beans. However, Maurice (so terrified that he stops thinking and acts instinctively) pounces on the rat king and destroys it. Maurice emerges from Spider's chamber carrying the body of Dangerous Beans. When he is safely out, he collapses and dies. In ghostly form, he sees the Bone Rat coming for Dangerous Beans and makes a deal with the reoccurring personality in Discworld, Death – two of his remaining lives in exchange for both his life and the albino rat's.
