<p class="ql-align-justify">It arrives in the morning. An old-fashioned airmail envelope addressed to Detective Nikki Galena. Inside, on a single sheet of blue airmail paper, are three words:</p><p class="ql-align-justify">&nbsp;</p><p class="ql-align-justify"><em>You failed me.</em></p><p class="ql-align-justify">&nbsp;</p><p class="ql-align-justify">The second airmail envelope arrives at Nikki's home address. The same message. Only this time, it's followed by four names: <em>Alexandra Cornfield, Ruth Baker, Bethany Lyons, Leanne Delaney</em>.</p><p class="ql-align-justify">&nbsp;</p><p class="ql-align-justify"><strong>Four missing women. Four local women whose bodies were never found.</strong></p><p class="ql-align-justify">&nbsp;</p><p class="ql-align-justify">The contents of the third letter, delivered by motorcycle courier, are even more disturbing.</p><p class="ql-align-justify">&nbsp;</p><p class="ql-align-justify">The letter leads directly to the discovery of a body buried in a shallow grave out on the Fens. And Nikki and her partner Detective Joseph Easter are plunged into a baffling murder investigation.</p><p class="ql-align-justify">&nbsp;</p><p class="ql-align-justify">Someone appears to be pursuing a personal vendetta against Nikki - and she has no idea who, or why.
