So I could go back as far as 2009 but I won't I. I'll start with I had a previous book on so I'm, I should say up front that I'm a China scholar. And I got interested in Cambodia actually, quite a long time ago, but I did not really have an opportunity to indulge it until I came to Cornell as faculty back in 2009 2008 rather, but I started the interest in Cambodia in 2009 so I just finished a book on China's foreign aid to the Khmer Rouge called Brothers in Arms, which was also published by Cornell University Press. And I was casting about for another for another project, and I had some stuff left over from that project. You know, I had some data, and I had some interest and momentum to essentially look at the structure of the Khmer Rouge movement after 1979 because that's something that is relatively understudied for, you know, for obvious reasons. And after about a year or so of casting about trying to figure out how to move forward on this I came about this close to giving up. I just thought, you know, I was on a I was on leave, I was in China. I was doing a little bit of research up in central North, northern part of the country, and I decided one night that, you know what? I'm just going to cut my losses and not move forward on this. After that, immediately after that stint in China, I went to Hong Kong, met with an old friend named Stephanie Giri, who works for the New York Times editorial page based in Hong Kong, and she said, Don't give up on it just yet. Talk to this scholar named Steve header, based in London, who I'd interacted with before. He'd been very helpful, but he was somebody whose time was quite valuable, and I didn't want to, you know, I didn't want to basically annoy him, you know, for a project that I was already, you know, pretty much, you know, 90% ready to put to bed. But I contacted him when I was in Cambodia right after Hong Kong, and it turns out I'd just been interested. I'd just been interviewing some ex Khmer Rouge soldiers earlier that day, trying to get a sense of which division reported to which command center. And it was really getting anywhere. And in an email exchange with Steve, he said that he basically sent me a an attachment which had all that information on and so we arranged to meet. I was up in cm, reap. We arranged to meet and put on pen. And Steve said, Look, I just retired. I got three or four books left in me, you know, if you want to write this one, then that's one less book I need to write. But he said, You got to do it. Got to do it correctly, you know, don't do it, you know, don't do a half baked project on. On this. And so what he did was, he very graciously invited me to come to London when, after he returned, where he had these, these archives that he had amassed over, you know, really decades that had been kind of legendary, that people were hoping to, you know, maybe get a sense of what was inside and all that. And Steve made, gave me access to them, and he did so with with some of his students as well. But what I did was I spent, got the so I was there in December. I spent, you know, the better half of a week just spending hours and hours and hours at the School of Oriental and African Studies scanning as many of these files as I could, you know, hundreds, even 1000s, of pages. And then I returned on subsequent visits to do that. Once I had this data, I not only felt that i i I had something to offer, but I also felt I had an obligation to do justice to this information and to the trust that Steve and others had put in, you know, you know, put in this project. And so there were a lot of fits and starts, you know, I chained jobs. I moved from Cornell to Johns, Hopkins, sais, of course, we had COVID. I worked as in a stint as Vice Dean for Faculty Affairs at SAIS. So this took a little bit longer than I than I hoped it would, but it was once, once I got that initial access to Steve's materials, when combined with the other data that I already had and would and would later compile as well, it created its own momentum. And so it really, you know, there I didn't look from that point onwards. I really didn't look
