SOLVED. Adult Historical Romance read in 2011. Husband is building a train through the jungle. There is some sort of mystery element where the villain makes death masks of his victims. [s]

Read around 2011. I remember the hero being very hot and cold with the heroine (maybe afraid of his feelings). I know that they were living out in the jungle while he built this railroad. The villain would make agonizing death masks of his victims.

I'm pretty sure this is The Tiger Prince by Iris Johansen.
