Sister Agatha: The World's Oldest Serial Killer

By: O'Donoghue, Domhnall

She's 118 years old, four steps from glory and now she's done playing nice.

Sister Agatha has lived a long, saintly life across three centuries-only to be told, during a routine check-up, that she's got just one week left to live. It's a bit of an inconvenience, really. You see, Sister Agatha once made a vow: to be the oldest person in the world. At last count, she was in fifth place. So close...

But where there's a will, there's a way, and the super-centenarian creates a bold Plan B.

Armed with little more than rosary beads, a fertile imagination and old-fashioned determination, Sister Agatha sets off on one final mission: to meet the four people standing between her and immortality and to gently expedite their demise. After all, vows are sacred.

And Sister Agatha? She will not go quietly...

A deliciously dark and delightfully funny romp across the globe, perfect for fans of Richard Osman.
