Malayaketu then decided to invade Pataliputra without Rakshasa by his side. He consulted the Jain monk Jiva-siddhi to decide an auspicious time for beginning the march. Jiva-siddhi, a spy of Chanakya, told him that he could start immediately. Jiva-siddhi also convinced him that Rakshasa was responsible for his father's death, but Bhagurayana persuaded him not to harm Rakshasa. Shortly after, Chanakya's spy Siddharthaka pretended to get caught with a fake letter addressed to Chandragupta by Rakshasa. Wearing the jewels given by Rakshasa, he pretended to be an agent of Rakshasa. The letter, sealed with Rakshasa's signet-ring, informed Chandragupta that Rakshasa only wished to replace Chanakya as the prime minister. It also stated that five of Malayaketu's allies were willing to defect to Chandragupta in return for land and wealth. An angry Malayaketu summoned Rakshasa, who arrived wearing Parvata's jewels that Chanakya's agent had sold him. When Malayaketu saw Rakshasa wearing his father's jewels, he was convinced that there was indeed a treacherous plan against him. He executed his five allies in a brutal manner.
