The Roosevelt Cottage, the fifth Big Bend Country Mystery, is nearing completion. It has taken longer than my previous novels because it was interrupted by another project: the 10th edition of my textbook Everything's an Argument.
I also needed to decide how the final book in the Big Bend Country Mysteries series (as yet, unnamed) will end so that The Roosevelt Cottage sets in place all the necessary plot elements. That final book may not take so long to write because it's already finished in my head.
FYI: Those of you familiar with Big Bend National Park likely know that the so-called Roosevelt cottages were built at the park by the Civilian Conservation Corps during the Depression, part of a nationwide effort back then to employ out-of-work young men during those tough times. Though the near-century-old stone buildings lack air-conditioning, the cottages are always in high demand with visitors who appreciate their charm and out-of-the-way location.
