Childproof

Things are not going well at R&P Laboratories. Not only is there a body in the biology lab and a staff member suspected of murder, but someone has broken in and wrecked their most important piece of equipment – the coffeemaker.
This is one case that is too close for comfort, so in "Childproof," the sixth R&P Labs mystery, the team of scientists-turned-detectives – Rob, Phil, Ellis, Virginia and Mitch – swing into action again to clear their colleague's name and find out what's in two mysterious bottles, why a quiet health-food advocate has a secret life as a mojito-drinking flirt and why vitamins have turned out to be very bad for someone's health.
