Barry the Sprout also appears in The Witches of Chiswick, at the time of writing Robert Rankin's latest novel.
Barry again appears in a supporting role, where he claims to be both a Phnaarg bio-construct and a guardian angel, tying up the loose ends of his previous appearances in a manner known as less-than-seamless. As in the Armageddon Trilogy, Barry has the power to time-travel, providing many cop-outs and minor temporal paradoxes when the author runs out of plot.
We are briefly introduced to Larry, Barry's well-meaning but incompetent twin brother, who has a habit of falling in with the wrong crowd.
