Mr. and Mrs. North solve murders. 'Dead as a Dinosaur' is the first I've read, and I enjoyed what the Lockridges, the husband and wife writing team, have created. We have a dinosaur museum, cave men and a dead scientist or two, which make for an unusual collection stuff, and the mystery gives the Norths much to puzzle over. The dialogue is witty. The suspects are interesting, and the first murder is insidious in its own special way.
This particular book comes well after the mystery series has begun and the main characters and their associations with the police are well established, but that doesn't hurt at all. The only drawback is the ending, where the crime-solvers and the suspects spend too much time moving from room to room during those final chapters, which turned out not to be as climatic as they should've been. But for an early 50's mystery it is worth the read and it's more engaging then some current mystery fiction.
