Loose Ends (The Hammer Commission #3)

Being on loan to the FBI has its advantages, and for the first time in far too long, Mark is taking a few weeks off with his family. But he's barely gotten started when he finds his brother unwittingly entangled in a mess that can be traced directly back to an attempt on Mark's life some months ago. An attempt that left something unexpected behind. And now that one loose end has started to fray into many and Mark must hurry to tie them all up, before unscrupulous drug dealers, power hungry witches, and even unwitting competitors of his brother's biotech company, unleash a power that could destroy hundreds, if not thousands of innocent lives.
