Bones Of The River [PDF ebook] 

‘Taking the little paper from the pigeon’s leg, Hamilton saw it was from Sanders and marked URGENT. Send Bones instantly to Lujamalababa… Arrest and bring to head-quarters the witch doctor.’It is a time when the world’s most powerful nations are vying for colonial honour, a time of trading steamers and tribal chiefs. In the mysterious African territories administered by Commissioner Sanders, Bones persistently manages to create his own unique style of innocent and endearing mischief.
