Christopher John Francis Boone is 15, a mathematical genius but he finds all social and physical interactions to be terrifying. This is because Christopher is autistic. He lives alone with his father, who told Christopher that his mother died of a heart attack two years ago.

His great love of animals causes him to go out one night to visit the neighbor’s poodle, Wellington, only to find it murdered. Since he’s found kneeling with the dog, he is initially accused of its death. When the policeman tries to calm him down, the touch causes Christopher to lash out and be arrested. The misunderstanding is cleared up, but he is left with a warning on his permanent record.

Discovering that others think the murder of a dog is too irrelevant to be investigated, Christopher decides, against his father’s strong wishes, to do so himself. This results in him having to talk to his neighbors, who to him are strangers, but he is determined to overcome his fears and solve this mystery.

While he does eventually find out the murderer’s identity, the journey to that information has him discover a huge family secret and embark on a journey that tests his resolve and the very limits of his abilities, challenging his autistic limitations.

“The Curious Incident of the Dog in the Night-Time,” opening the 2017-18 season at Indiana Repertory Theatre, is based on Mark Haddon’s critically-acclaimed 2003 novel of the same name. It won the 2015 Tony for Best Play. However, due to the novel being written in first-person and the production of it needing to have the various characters fleshed out and enacted, many technical alterations were made to bring the tale to the stage.

Shiobhan (played by Elizabeth Ledo), one of Christopher’s teachers, reads much of his inner dialogue from a notebook. He has written the story there in hopes of turning it into a book once it has concluded.

Much of the cast morphs from one character to another while also voicing the self-doubts and thoughts of Christopher. The medium of stage allows for non-linear and abstract elements required to tell the story, and even briefly goes “meta” with the cast discussing the play as themselves with Christopher.

This production includes IRT’s landmark casting of Mickey Rowe as Christopher, making him the first American actor with autism in the role. Familiar faces Robert Neal and Constance Macy portray his father and mother.

The entire cast, which also includes David Alan Anderson, Margaret Daly, Mehry Eslaminia, Eric Parks, Gail Rastorfer and Landon G. Woodson, do an impeccable job, true to the standards of an IRT performance.

Thought-provoking and surprisingly relatable, this drama brings you on an unusual journey through a unique mind, as well as through the English countryside and heart of London. And when you go, be sure to stay after the curtain call for a unique, and highly entertaining, mathematical encore.

No dogs were actually harmed in the making of this play, which runs through Oct. 14. Find the IRT at 140 W. Washington St. downtown or online at irtlive.com.
