Jupiter's gold

the long version

"1863 - It all begins with the murder of a customs officer and in the days that follow there will be others, yet apart from the mode of their deaths there will be little to connect them. As if a multiple murderer isn't enough, Superintendent Jarrett, Inspector Grant and Sergeant Quinn of the Detective Department at Glasgow Central have to contend with upper class thieves targeting jewellery shops and an archaeologist with a taste for the high life. Are these crimes linked? And what does a worthless lump of stone attract the attention of ruthless men who will stop at nothing to locate the hiding place of Jupiter's Gold?"--Publisher description.
