Or "How we found the bishop's bird-stump at last." A hilarious novel by
Connie Willis. The plot revolves around an attempt to use Oxford's time-travel facilities to locate a (
dreadful) family heirloom that was lost by the rich patron of a church. The novel is set in the same universe as "
Domesday Book," but it's not horribly depressing.
The title comes from
Jerome K. Jerome's novel "
Three men in a boat, to say nothing of the dog."
