To say nothing of the dog : how we found the bishop's bird stump at last
(Book club Kit, Reference Book Club)

Ned Henry is badly in need of a rest. He’s been shuttling between the twenty-first century and the 1940s in search of a hideous Victorian vase called “the bishop’s bird stump” as part of a project to restore the famed Coventry Cathedral, destroyed in a Nazi air raid. But then Verity Kindle, a fellow time traveler, inadvertently brings back something from the past. Now Ned must jump to the Victorian era to help Verity put things right—not only to save the project but also to prevent altering history itself.
