Giant Rat of Sumatra

The Giant Rat of Sumatra is a fictional giant rat, first mentioned by Arthur Conan Doyle in "The Adventure of the Sussex Vampire". As part of the tale, the protagonist, Sherlock Holmes, declares that there is a "story" connected with this rat, presumably a detective case he has handled. The name of the rat and its implied unpublished history were later used in works by many other writers.

Original reference
In "The Adventure of the Sussex Vampire", first published in the January 1924 issues of The Strand Magazine in London and Hearst's International Magazine in New York, Doyle has Sherlock Holmes declare, as an aside, to Dr. Watson:


 * Matilda Briggs was not the name of a young woman, Watson, ... It was a ship which is associated with the giant rat of Sumatra, a story for which the world is not yet prepared.

How the ship, the mammal, and the Indonesian island are associated is not specified. Rats commonly colonize ships, and so there is an obvious line of speculation.

Another train of thought follows the reasoning that Matilda Briggs actually was the name of a young woman as well as a fictional ship – for the famous "mystery ship", the Mary Celeste, which was found abandoned at sea in 1872, had sailed under the command of Captain Benjamin Briggs, whose daughter, Sophia Matilda Briggs, was a passenger on the doomed merchant brigantine. Doyle was certainly familiar with the Briggs family, for in the January 1884 issue of the Cornhill Magazine, when he was but a 25-year-old ship's surgeon, he had published a short story about the mysteriously abandoned Mary Celeste titled "J. Habakuk Jephson's Statement". As it was a work of fiction, Doyle did not adhere strictly to the facts; he renamed the ship Marie Celeste, the captain's name was given as "J.W. Tibbs", and the fatal voyage was said to have taken place in 1873 – but his story proved so popular and influential that many people to this day still refer to the vessel as the Marie Celeste, rather than the Mary Celeste.

Giant Indonesian rats
A number of species of large rats have existed and, in some cases, still live on Sumatra, Papua, East Timor, and other Indonesian islands:


 * In 1983, the Mountain Giant Sunda Rat (Sundamys infraluteus), which is only somewhat larger than a Norway rat, averaging around 0.3 kilograms in weight, was actually referred to as the "giant rat of Sumatra" in an article in The New York Times.
 * In a lecture delivered in 1994 and published online in 2014, Holmesian Alan Saunders argued that a giant Sumatran rat species was being used by the villain Culverton Smith as the carrier of the disease known as Tapanuli Fever, a feature of Doyle's "The Adventure of the Dying Detective". (Tapanuli is an administrative district of North West Sumatra; the highly lethal infectious disease is also known as Melioidosis; it is caused by the bacterium Burkholderia pseudomallei.) Saunders identified the rat as the Large Sumatran Bamboo Rat (Rhizomys sumatrensis); this species can reach lengths of nearly 50 cm with a 20 cm tail, and weigh up to 4 kilos (8.8 lbs); it is in real life a carrier of the disease-causing mold, Talaromyces marneffei, which can also be lethal.
 * A new species in the Woolly Rat (Mallomys) genus was discovered in 2007 in the Foja Mountains of Papua; it weighs 1.4 kilograms (3.1 lb) and has been compared to Holmes's animal.
 * In 2015, the discovery of fossils of "seven new species of giant rat", including the "largest rat ever" on the island of East Timor was announced. The biggest of these Coryphomys rats was described as weighing "5 kilos (11 pounds), the size of a small dog," and was referred to as the "Giant Rat" in news stories.

In Sherlockiana
A number of authors of Sherlockiana have endeavoured to supply the missing adventure of the giant rat of Sumatra, either in non-canonical Holmesian fiction, or as references to the tale in other fictional settings:


 * In "The Giant Rat of Sumatra," an episode of the radio series The New Adventures of Sherlock Holmes written by Edith Meiser, and first broadcast on 1 March 1942, Professor Moriarty arranges for the titular rodent, infected with bubonic plague, to be transported to England on board the Matilda Briggs. This episode is apparently lost, but is described in some detail by Jim Harmon in his book The Great Radio Heroes.

During the course of the narrative, Holmes mentions that Professor Challenger helped solve the case of the giant rat, although the actual name of the case is not stated.
