Sir Thursday

Synopsis

The book begins with Arthur Penhaligon and Leaf attempting to return to Earth after their adventures in the Border Sea. While Leaf is able to pass through the front door and return to Earth, the presence of a Nithling duplicate of Arthur prevents him from doing so, and he is forced to remain in the Lower House.

Dame Primus then informs him that Mister Monday and Grim Tuesday have been assassinated. Moments later, he is drafted into the Glorious Army of the Architect – wherein everyone living in the House must serve for 100 years – which is based in the chessboard-like demesne called the Great Maze. The leader of the army is the Fourth Trustee of the Will, Sir Thursday, a Denizen afflicted with the deadly sin of wrath. The army is currently involved in a campaign against the Piper, who is trying to claim the Fourth Key.

Within the army, Arthur is soon mistaken for a Piper's child and has his memory wiped, along with his friend Fred Initials Numbers Gold – a real Piper's child. One month later and during the first battle against the Piper's New Nithling army, Arthur begins to recall his identity. The entirety of it is recovered later in the book when an officer mentions his name and title.

On Earth, Arthur's double, known as the Skinless Boy, has thrown a hospital near Arthur's home into panic by infecting staff and patients with a fungoid, extraterrestrial life-form which allows him to read and eventually control their thoughts and actions. This fungus, nicknamed Grayspot, is mistaken for a biological weapon, and the hospital put under quarantine. Leaf infiltrates the hospital, seeking to obtain and destroy the magical object used to create the Skinless Boy: a pocket torn from one of Arthur's shirts. She succeeds, but is infected by Grayspot in the process. She then leaves the hospital, only to find that the House has appeared above it and cannot be reached from the ground. With the help of a retired pharmacist named Sylvie, Leaf makes her way to Arthur's house where she uses a special telephone to contact Arthur's friends and get help, just as the fungus gains full control of her body.

Suzy Turquoise Blue arrives and takes the pocket to the House. There, she finds Arthur and Fred, and joins them in a raid led by Sir Thursday to find and destroy the New Nithlings' weapon, which is preventing the mechanical floor of the Great Maze from shifting. Arthur destroys the weapon by throwing the pocket into it, simultaneously destroying the Skinless Boy. As Arthur escapes from the Piper with Sir Thursday, he distracts Thursday enough for the fourth part of the Will, a snake embodying the virtue of justice, to break free, whereupon it makes Arthur the Bearer of the Fourth Key – a sword or baton depending on whether or not the wielder is in combat – and Commander of the Glorious Army of the Architect. With help from Dame Primus and others from the lower demesnes, Arthur defeats the New Nithling army.

On Earth, Leaf wakes up in a hospital a week after the Skinless Boy was defeated. She soon learns from a nurse that the Grayspot has disappeared and that Lady Friday, another Trustee, has become a doctor on Earth.

Themes

As with the previous books in the series, the themes of seven, sin and virtue are prevalent throughout Sir Thursday providing the personality characteristics for many of the main characters.

In Sir Thursday, readers are also introduced to the power issues that Arthur begins to struggle with – his natural compassion and desire for fairness and kindness, against the characteristics displayed by other senior denizens and Dame Primus, and the influence of the key. In addition, the idea of Arthur losing his mortality and becoming an immortal Denizen of the House, represented by the silver/gold crocodile ring that was introduced in Drowned Wednesday, is further explored, with Arthur often choosing to refrain from using the key – and the power it represents – to ensure he remains human.

The book also loosely explores the dangers of anger, and actions taken in anger. It is only Sir Thursday's loss of control and subsequent murder of two Piper's Children that allows Arthur to gain control of the Fourth Key, assisted by Thursday's Dawn, Noon and Dusk.

Critical reception

The book received generally favourable reviews. It is ranked 4 stars by Amazon users, and The Times stated "Nix's imagination is matched only by his prose style."

In particular, the book was praised for its originality, intricacy, action and characters. VOYA says that the book "..is well written, action packed, imaginative, and full of quirky memorable characters...", and Children's Literature agrees that "It is a readable choice..." The School Library Journal also extensively praised the book, saying "Reluctant or 'hard to fit' readers will find this series enjoyable, as Nix is able to create vivid pictures in the minds of his readers. Fans of the fantasy genre will appreciate these books for their strong continuity, believable characters, and edge-of-your-seat-action. This offering complements the series’ well-established structure."

The book did, however, receive consistent criticism. The most common complaint was on the speed of the plot – the School Library Journal summarises all the comments, saying that "the events move a little slower than in previous installments..." – and the difficulty in entering the series without reading all the previous books first: VOYA simply says "readers attempting to enter the series through this volume are likely to be quickly lost." Children's Literature also criticised the repetition of previous content, saying there is "..entirely too much front matter [which] sags with the necessity of replaying earlier story lines."
