The World's Greatest Detective and Her Just Okay Assistant

The World's Greatest Detective and Her Just Okay Assistant by Liza Tully:

On the night of her sixty-fifth birthday party, Victoria Summersworth somehow fell over her balcony railing to her death on the rocky shore of Vermont’s Lake Champlain. She was a happy woman—rich, beloved, in love, and matriarch of the preeminent Summersworth family. The police ruled her death a suicide, but Victoria’s daughter Haley thinks it was murder.

Merritt (detective) and Olivia (new assistant) soon discover that the Summersworth family is complicated web of lies, ambitions, and resentments. As the list of suspects grows, Olivia makes one apparent mistake after another. 

Tully has written an entertaining mystery novel, however, it would have been a better book without the anti-fat bias and homophobia running through the plot.
