A Deceit of Lapwings

Three murder scenes; two causes of death; one body. It is a case that would challenge Domenic Jejeune even under the best of circumstances. But his DCS's temporary absence means that Jejeune must work under Marvin Laraby, an ex-superior with whom he has a particularly fractious history. Jejeune and Laraby must work together to discover why a ruthless land contractor would want to invest in new bird migration software, and what possible interest the death of a birding app developer could be to the British intelligence services. With the appearance of Lindy's ex boyfriend disrupting Jejeune's private life, and Danny Maik dealing with divided loyalties, is this the case that finally defeats Domenic Jejeune?
