guards! guards! - terry pratchett

a funny little book about how sam vimes meets his future wife, Lady Sybil- she breeds dragons, she is from the ankh morpork nobility ['old money'], she wears old clothes but they were fashionable once and still have an aura of 'nobility', she is the only one who seems to have some knowledge of the dragon which is charboiling the city and residents of ankh with its dragon breath.......

the huge fire breathing ['draco nobilis'] dragon is summoned from its 'dimension' by a secret society. the leader of the society is keen on ruling ankh with the support of the dragon. his followers in the society are people in small-jobs with big egos. the followers have been chosen because of their ability to be led like sheep by working on their frustrations and grievances. the magic chant to summon the dragon is in a book in the library of the unseen university, but as the librarian [an orangutan] discovers to his horror: the book had been stolen!

a new recruit to the ankh police is carrot- a human raised by dwarfs. the patrician - the current ruler of ankh- who has been imprisoned by the dragon in his own palace dungeons, extracts a cleverly concealed key in the dungeon and gets back to the remains of his office. carrot's heroics -as well as that of sam vimes and his team of police officers- saves the day and the patrician graciously gives them a more important role to play in policing the city.

since the dragon had burnt down the original 'police hq' of ankh, Lady Sybil has donated one of her huge properties in the city for use as the new police hq.

the 'draco nobilis' is found to be of the female order and is tamed by one of the dragons bred by Lady Sybil.'

so all's well that ends well!!!!
