Maureen Johnson is the #1 New York Times and USA Today bestselling author of many young adult novels, including the very murderous Shades of London series and the Stevie Bell mysteries: Truly Devious, The Vanishing Stair, The Hand on the Wall, and The Box in the Woods. She has also done collaborative works, such as Let It Snow with John Green and Lauren Myracle (now a movie on Netflix), and several books in the Shadowhunter universe with Cassandra Clare. Her books have been translated into more than thirty-five languages. For safety’s sake, she lives in New York City; the vicar cannot reach her there.

Jay Cooper’s books don’t normally include grisly murders, nefarious deeds, or corpses of any kind. He has written and/or illustrated more than twenty books for kids, including The Spy Next Door, The Pepper Party, and the Bots series, and has contributed work to the New York Times bestselling series The Last Kids on Earth. Currently he is illustrating a graphic novel entitled Super Atomic Wombat Girl. He’s also a graphic designer of theatrical advertising, and has worked on more than a hundred Broadway musicals and plays (which have heaps of deaths).
