Blake Pierce writes thrillers with female agents (usually FBI, but also police, and Interpol) confronting serial killers. Left To Hide is number 3 in the Adele Sharp series, and it has the usual marks of Pierce's plot: agent can't solve crime, gets in trouble with boss(es), risks life and limb to catch killer, then tries to catch up with chaotic personal life (usually husband, father, mother). Adele Sharp is a little different in that she is trilingual and a citizen of the US, France, and Germany. She gets called in to solve multinational crimes. Pierce handles those settings fairly well, with a little suspension of disbelief... The character of Adele is well, sharp. I recommend the series as well, if you like fast-moving stories, solid writing, and variations on the plot I outlined. Very twisty and peculiar variations...
