Three Men in a Boat - Jerome K Jerome

Three Men in a Boat is a classic tale of lighthearted comedy and misadventure by Jerome K. Jerome.
Also known by its full title: Three Men in a Boat (To Say Nothing of the Dog), this book follows the escapades of three fellows named George, Harris and Jerome. The latter, being the author himself, is referred to only as 'J' throughout the story.
The trio contrive to journey along the Thames in what they intend to be a easygoing boating holiday. The three friends all claim to share various illnesses and to suffer from overwork. Upon agreeing to make their way up the River Thames they bring along J's dog, Montmorency, for the ride too.
Jerome mainly sticks to the story of the river journey, but also includes much humorous digression, usually taking the form of memories of past amusing events, into the tale. Highlights include the trio's miserable attempt at making Irish Stew from leftovers at the campfire, and a trout made from Plaster of Paris.
The book, first published in 1889, was a big success among late Victorian audiences, but attracted scathing reviews from critics who found its informality and use of slang to be very vulgar. However among the everyday reader the book was an enormous success, with sales strong for decades after its publication.
Unusually for books of the era, the humour has dated well - the believable friendship and banter between the blokes aboard ship continues to resonate with the modern audience, while several of the comic set pieces carry an eternal lighthearted humour.
