<b>Welcome to the award-winning adventures of FBI Agent Victoria Heslin. Each <i>“can’t-put-it-down”</i> book in the series features a different investigation and can be read as a standalone.</b> <br> <br>A key FBI witness is found dead in his kitchen with strange messages written on his forehead: the word “liar” and “2.” <br> <br>Agent Victoria Heslin is assigned to investigate. Her boss believes the murder is a hit to silence the witness, but the facts Victoria discovers say otherwise. As she follows the leads, calls start coming in—more dead bodies, each corpse left with a different message.

And another. <br>The authorities in D.C. and Virginia are panicking about the rising body count.
