Professor Percival Tunstell is a major character in the The Custard Protocol. He is a childhood friend of Rue and the twin brother of Primrose.

Percy is son of Baroness Ivy Tunstell, a vampire queen, and Ormond Tunstell, a former claviger for the Woolsey Pack and actor.


Percy is good looking, with red hair and pale skin from the many hours he spends inside reading. He is gangly and awkward, and wears spectacles. Inexplicably, he is attractive to debutantes.


Quesnel Lefoux calls him "Pompous Percy." Percy hates that he is inexplicably attractive to debutants, so he hides indoors and his only interest is in books. He is a good strategist and technician, good at coming up with redundancies and backup plans.


As soon as Percy came of age, he moved out of his mother's hive and accepted a post as an Oxford don. His time at Oxford didn't last; he was dismissed for radical theories on the transcendental sprout-shaped nature of the aetherosphere. Afterwards, he moved into a home behind the British Museum, off Russell Square.

In the booksEdit

Timeless Edit

In Timeless, Percy travels with his family to Egypt, along with the Maccons. His sister Primrose is mistaken for Prudence and kidnapped by the Alexandria Hive. She is later rescued by the adults of both families, and escapes unharmed, though their mother is fatally wounded in the attempt and is metamorphosed into a vampire queen while there.

Prudence Edit

Rue invites Percy to become the researcher, librarian, and navigator aboard The Spotted Custard. Percy agrees, and travels to India with Rue and her crew.

Imprudence Edit

At the beginning of Imprudence, Rue, Primrose and Virgil are worried because Percy had taken off in a huff. They discover him in the library aboard the Spotted Custard in a near-rage over a paper Quesnel had done, but refusing to talk about it. Quesnel had published a story in the Royal Society with Mrs. Featherstonehaugh about the weremonkies before Percy, which is why Percy was so upset. In retaliation he published his own paper on the werecats. When this fact is discovered while the crew is in Egypt, it leads Rue to believe the attacks on the ship have been an effort to capture Tasherit. Percy becomes very contrite and does his best to make up for his bad behavior.

  • "Now, Puggle, he's the best man for the job of navigator in all of London. Who's not already committed to queen, country, or contact. Do be reasonable. He's smart and capable and used to being bossed around by a woman." (Prudence, Chapter Two)
  • "Percival Tunstell was nothing if not a great fan of learning. If that education involved sharp pointy sticks, he applied himself just as diligently as to other forms of research and with far more uncomfortable results to those around him. In the end, Queen Ivy gave up mothering her son, and Percy stopped poking her vampires with letter openers." (Prudence, Chapter Three)

Presumably these represented the eligible among the officers' and ambassadors' daughters. Percy, as usual, had drawn them to him like jam to toast." (Prudence, Chapter Eight)
  • “The Rakshasa,' said Percy pedantically, 'are a different breed altogether from our vampires. Much in the same way that poodles and dachshunds are different breeds of dog. Rakshasas are reviled in India. Their position as tax collectors is an attempt by the crown to integrate them in a more progressive and mundane manner. Rue said, 'Oh, how logical. Because we all know ordaining someone as a tax collector is the surest way to get them accepted by society.” (Prudence, Chapter Nine)
