A bed of scorpions (First edition.)

Boxing Day. A dead body has been found in the chemistry department of Queen's University in West London. Tom Chambers, the head of department, was known to have a bad heart, and had it not been Christmas, no questions would have been asked. What was a procedural post mortem soon turns into a murder investigation when it becomes evident Chambers had been injected with a dangerous amount of digitalin. Publisher Samantha Clair is once more propelled into a crime investigation when her star author, Breda McManus' husband and physics professor, asks for her help.
