Wetworld (novel)

Publisher's summary
When the TARDIS makes a disastrous landing in the swamps of the planet Sunday, the Doctor has no choice but to abandon Martha and try to find help. But the tranquillity of Sunday's swamps is deceptive, and even the TARDIS can't protect Martha forever. The human pioneers of Sunday have their own dangers to face: homeless and alone, they're only just starting to realise that Sunday's wildlife isn't as harmless as it first seems. Why are the native otters behaving so strangely, and what is the creature in the swamps that is so interested in the humans, and the new arrivals? The Doctor and Martha must fight to ensure that human intelligence doesn't become the greatest danger of all.

After getting it wet, the paper identifies him as both a  door-to-door carpet cleaner salesman and as "Madame Romana, Astrologer to the Stars".  It's unclear whether this is a reference to his former companion or merely the Romany people he later mimics, who are so closely associated with fortune telling on Earth.
