Writing as: Craig Dirgo

According to Wikipedia, Craig Dirgo got into writing through Clive Cussler, whose fantastic car collection proved a magnet to a young man. From there he became involved in some of Cussler's NUMA projects and worked with the famed author on a couple of non-fiction books before creating his own spy character. Mr. Dirgo is also the co-author of the first two books in the Oregon Files series.
