Annie, Dan & the Android Man

... Deep within the bowels of Edinburgh Castle something sinister stirred. A dark shadowy figure in a grubby laboratory coat chuckled deviously as he stood in front of the rows of test tubes on the bench in front of him each containing a potentially lethal mixture when combined with one or several of the others ... When Katherine McKitten‘s Great Aunt Annie starts acting a bit strangely, she and her friend Heather Sweeney investigate and discover something strange going on beneath Edinburgh Castle. They enlist the help of a young police officer, DC Alexander James, who is relatively new to the Edinburgh Police force; and together they uncover a plot so fantastic that it seems to have come straight off the pages of a science fiction novel.
