Vechel Howard was a pseudonym for Howard Vechel Rigsby (1909-1975), who wrote in a variety of genres, including westerns and gothic romances.
Murder With Love is the first adventure for PI John Church and, according to Mystery File, "it's one of those cases that gets him so personally involved that you wonder when it's over whether there will ever be another one." There was one more, Murder on her Mind, but that was the end for this long-lost, hard-boiled crime series, finally back-in-print after 60 years.
