A dead baron, an Irish castle, and an unexpected ghost . . . Charlie Harris, Helen Louise Brady, and their feline friend Diesel find themselves hot on the trail of a conniving killer in this delightful Cat in the Stacks Mystery from New York Times bestselling author Miranda James.

Charlie Harris and his wife, Helen Louise Brady, have arrived in Ireland for their honeymoon. After a few days in Dublin, they head to County Clare, ancestral home to Helen Louise’s extended family, the O’Bradys. Her cousin Lorcan runs Castle O’Brady as a bed-and-breakfast with his wife Caoimhe and their daughter and son-in-law.

The dead man is centenarian Finn, Baron O'Brady, Lorcan’s grandfather, which means that Lorcan now becomes the new Baron O'Brady.

And why is a ghostly cat making an appearance in their room-is he trying to warn them? Charlie and Helen Louise must answer these questions and more as they realize the local garda can't solve the crime alone. And along with Diesel they will have to investigate themselves or risk something wicked coming their way…
