The Lone Island Mystery

By Emylia Hall

A wealthy family. An isolated island. A dead body. Is it a tragic accident or foul play? The Shell House Detectives are investigating again...

Lone Island is a remote and windswept spot, but for nature reserve warden Pippa Grant it's always been a haven. Until a body washes ashore--and she's the one to find it.

The police believe the deceased, Axel Marks, accidentally fell from the cliffs near Porthmerrin House, the grand estate on the mainland where Axel's mother once served as housekeeper to the Grey family. But Pippa is adamant that there's more to Axel's death, and begs Ally and Jayden, the Shell House Detectives, to take the case.

Soon it emerges that Axel had a troubled past, and a complicated history with both Edward Grey and his son, Lucas. As the reasons behind Axel's visit to Porthmerrin become clear, Ally and Jayden feel sure that the house holds the key, and both owners and staff come under scrutiny. But when the police switch their focus back to Lone Island, Ally and Jayden are forced to question whether it's their client who has something to hide.

Was Axel murdered out of jealousy and greed, or because of an ancient betrayal? And how far will the killer go to achieve their ultimate goal? As Ally and Jayden finally bring the devastating truth to light, it's clear that Axel's death was just the beginning of the story...
