The Pregnant Virgin - Richard West, #6

While investigating the unexplained absences of students in the Rickmansworth District, Richard finds several cases where the pregnancies of vulnerable women cannot be explained;  Some women describe bright lights and little green men.  While solving the mystery  Richard becomes a target for a sophisticated international network of criminals. I have just finished reading"The Pregnant Virgin". It is a great read.
I loved that it was set around Dunedin. I didn't want to put it down. The twists in the plot kept me guessing. A book I would thoroughly recommend to other readers.  Gael Trevathen.
