Tidy Killing

This was the tidiest murder Simms has ever seen. The body lay on the spotless floor of a spotless laboratory, an overturned chair, a flask oozing green muck, the only signs of anything out of order. During his investigation Simms encounters many mysteries: scientists with spotless records; a wildlife photographer fond of dogs; a damaged young woman with perfect memory and, finally, a cold blooded killer with an unshakable alibi. He finds not only the answer to all his questions but also a satisfying friendship with an attractive and highly intelligent woman.
