The novel “The Last Dodo” by Jacqueline Rayner was published for the first time in 2007.

After a discussion about zoos, the Tenth Doctor and Martha Jones take inspiration from an electronic guide to the creatures of the Earth and decide to go in search of a living dodo. The Doctor programs the Tardis to find a dodo but the two travelers end up in a sort of museum of the last specimens of all the extinct species.

Their arrival isn’t exactly well received because they get mistaken for specimen thieves. For some time, someone has been stealing many of them and no one can figure out how. Despite being in a gray area from the ethical point of view, the Doctor and Martha decide to help the museum to solve the mystery.
