Little wonder then that Cicero was finding it so hard to compose his inaugural address, and that when we returned to his house from the river and he tried to resume his dictation his voice kept on trailing off. He would stare into the distance with a look of abstraction on his face and repeatedly wonder aloud why the boy had been killed in such a manner, and of what significance it was that he belonged to Hybrida. He agreed with Octavius: the likeliest culprits were the Gauls. Human sacrifice was certainly one of their cults. He sent a message to a friend of his, Q. Fabius Sanga, who was the Gauls' principal patron in the senate, asking in confidence if he thought such an outrage was possible. But Sanga sent rather a huffy letter back within the hour saying of course not, and that the Gauls would be gravely offended if the consul-elect persisted in such damaging speculation. Cicero sighed, threw the letter aside, and attempted to pick up the threads of his thoughts. But he could not weave them together into anything coherent, and shortly before sunset he called again for his cloak and boots.

I had assumed his intention was to take a turn in the public gardens not far from the house, where he often went when he was composing a speech. But as we reached the brow of the hill, instead of turning right he pressed on towards the Esquiline Gate, and I realised to my amazement that he intended to go outside the sacred boundary to the place where the corpses were burned – a spot he usually avoided at all costs. We passed the porters with their handcarts waiting for work just beyond the gate, and the squat official residence of the carnifex, who, as public executioner, was forbidden to live within the precincts of the city. Finally we entered the sacred grove of Libitina, filled with cawing crows, and approached the temple.
