I have just recently discovered books by this author and am enjoying reading the Aurora Teagarden Mystery series which this book is from.  Aurora and her husband, Martin, are surprised one day when Martin's niece, Regina, shows up with a baby.  They put her up in an apartment above their garage and then go to a dinner party.  When they come home they find Regina missing, her husband dead on the stairway to the apartment and the baby sleeping under the bed.  This is only the beginning......  There is a lot more mayhem to occur in this story.  This is not an all's well that ends well story so read to the very end to find out if your predictions of who done it are correct and if you were able to guess how this story ends.
