Tyler 'Ty' Haringa is an agent with the U.S. State Department.
That is the likely employer but we are not told definitively that he is an employee, only that he and his partner had been sent by that government bureau. When we meet him again a bit later, he is on a small Mediterranean island working with a woman from the "Intelligence Department" so our guess about the employer is just that.
As we encounter him in the first recorded adventure, he is being introduced to a beautiful young woman who also happens to be a Princess and Haringa is able to land his foot solidly in his mouth in his opening words to her; he calls her 'Honey' right off the bat, winks at her leeringly, and then brags how "the State Department wouldn't send any but the best". Since his presence there was to provide the "best" in security and within two minutes of that chauvanistic introduction, his partner stumbles into the room dying of gunshots and the Princess is whisked away by kidnappers, his attitude seems a bit out of place. Certainly it is not the most auspicious way to meet a 'hero'.
Inside the next couple of pages, he meets a 19-year old waitress at a falafel shop, questions and beds her and then heads to a meet with a Russian hooker whom he questions and beds; both women are left panting with incredible satisfaction from the encounter. It is interesting to note that when Haringa winds up in the hospital not long after this, it is from gun shot wounds, not exhaustion.
The second adventure he is not as 'forthright' as he is in the first but then again, as we come upon him in that mission, he is suffering from a head injury and having a bit of a memory problem. As his recent memory returns, so does his swagger.
We do not learn very much about the history of Haringa from the two short adventures we have of him. The injuries he suffers in both stories notwithstanding, he definitely is able to get the job done.
