The boys from The Erimus Detective Agency are back in the funniest adventure to date. The search for an ancient Celtic Cross - The Lindisfarne Liturgy - saved from the marauding Vikings and missing for centuries. Could this cross have somehow ended up on Teesside? Sam, Phillip and Albert assisted by their friends, attempt to discover its whereabouts, while simultaneously trying to wrestle with the vicissitudes of everyday life. A hilarious romp containing canine offspring and Pilates. Spikey auras and misaligned chakras. Orange shirts and cravats. Monogrammed flip flops, waders and fishing flies. Irate coppers, monocles and puppy pads.

A side-splitting adventure from beginning to end. Will the boys find the cross, or will they be thwarted by a collection of individuals intent on owning it? Mystery and intrigue have never been more enjoyable!.
