Retired police detective Lulu Lewis’s life changed forever when she met a street cat named Conrad.

There’s something very special about Conrad, but it’s a secret she has to keep to herself. When Lulu takes her narrowboat to Oxford, she is planning nothing more stressful than attending a friend’s birthday party. And drinking a few glasses of Chardonnay.

But a brutal murder and a daring art theft means her plans are shattered – instead, she and Conrad find themselves on the trail of a killer...

A killer who may well strike again.
