He nodded. The plan was that Cadal and I should be landed on the side of the estuary away from Maridunum, at a point I knew from which we could make our way unseen to join the road from the south. We would be travellers from Cornwall; I would do the talking, but Cadal’s accent would pass with any but a native Cornishman. I had with me some pots of salve and a small chest of medicines, and if challenged could pass as a travelling doctor, a disguise that would serve as a pass to more or less anywhere I wanted to go.

Marric was still on board. He would go in with the trader, and disembark as usual at the wharf. He would try to find his old contacts in the town, and pick up what news he could. Cadal would go with me to the cave of Galapas, and act as connecting-file with Marric to pass over what information I got. The ship was to lie for three days in the Tywy; when she sailed Marric would take the news back with her. Whether I and Cadal would be with him would depend on what we found; neither my father nor I forgot that after Camlach’s part in the rebellion Vortigern must have been through Maridunum like a fox through a hen-run, and maybe his Saxons with him. My first duty was to get news of Vortigern, and send it back; my second to find my mother and see that she was safe.

It was good to be on land again; not dry land, for the grass at the head of the ridge was long and soaking, but I felt light and excited as the boat vanished under the mist and Cadal and I left the shore and made our way inland towards the road. I don’t know what I expected to find in Maridunum; I don’t even know that I cared overmuch; it was not the homecoming that made my spirits lift, but the fact that at last I had a job to do for Ambrosius. If I could not yet do a prophet’s work for him, at least I could do a man’s work, and then a son’s. I believe that all the time I was half hoping that I would be asked to die for him. I was very young.
