This is the sixth book in the popular John Eisenmenger and Helena Flemming forensic mystery series - new from Severn House.Reluctantly, Eisenmenger takes a job as a locum in the pathology department of St Christopher's Hospital as his partner Helena is pregnant and they must prepare financially for the baby's arrival. John finds the prospect of being back on the treadmill, working within the NHS again, tedious, but when he is unwilling to accept his boss' 'death from natural causes' diagnosis after autopsies on various bodies, his professional suspicions are piqued. He goes to his old friend DI Beverley Wharton with his concerns and when all paths seem to lead to Atopia, a private clinic for the treatment of allergies run by a Dr Adam Dreifus - whose wife has just been found dead - it seems that there is more to this than 'death by natural causes'...
