Sherlock Holmes and the Vampire Invasion

Mycroft's exclusive Diogenes Club is targeted, its members being found drained of all blood, their necks punctured with wolf-like teeth marks. The vampire murderer is combing the workhouses for the most desperate and misplaced, forming a vampire army in Victorian London. Wiggins is on the case. Would a murderer who kills indiscriminately stop at children? Sherlock is aghast to learn that Mirabella has disappeared, secretly checking into a workhouse in an effort to find the vampire murderer¿and the reason for these killings. It's the dawn of medicine when knowledge of human anatomy is almost non-existent, without which understanding there can be no surgery, no blood transfusions, and no advancement. Dead bodies are in high demand to further the needs of science. If a body were helped along to its final resting place and thereafter removed from the coffin, who was going to be the wiser?
