Who Killed My Dog: An Investigation by Lucy Hamilton

When Lucy Hamilton finds her beloved golden retriever, Peru, dead beside the garden shed on the coldest morning of winter, the police close the case within the hour. Natural causes, they say. Lucy does not believe them.

Armed with a notebook and the discipline of someone who has read every detective novel she could find, Lucy begins her own investigation. Every person in the Hamilton household becomes a suspect. Her older sister, who resented Peru's barking. Her brother, who was burying something in the backyard in the dark. The family servant, whose timeline keeps shifting. Her father, whose private phone calls and locked study suggest a secret he has been carrying alone. And her best friend, who claims she was home all night but was not.

One by one, Lucy interviews them. One by one, their secrets surface. None of them are small. None of them are what she expected.

The truth, when it arrives, does not come from a stranger. It comes from inside the house, from the person everyone trusted most, and it carries a cost that Lucy could not have calculated when she wrote the first line in her notebook eleven days earlier.

Who Killed My Dog is a closed-family mystery about grief, loyalty, and the particular cruelty of secrets kept by people who love each other. It is also a story about a dog who knew the truth and would not stop trying to tell it.
