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 will need to combine their skills 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?
