Unnatural causes - Leah Ruth Robinson

Dr Evelyn Sutcliffe spends her working day keeping death at bay, but now it intrudes into her home. The life-and-death contest waged daily in the ER is a constant part of her existence, so home represents a refuge from frenzy, anxiety, uncertainty -- and blood. But now a dear friend and colleague is left clinging to his life by the barest of threads, struck down by poison he ingested while cooking in Evelyn's Manhattan apartment kitchen. On a night when she was supposed to be celebrating, she's back in the emergency room frantically trying to save a life, and forced to accept three facts: there's a killer near at hand, and the killings have only just begun . . . and maybe she is the intended victim.
