Lucky Luke (english version) - Volume 65 - Ghost Hunt

In the Old West, there’s nothing strange about a stagecoach getting robbed.
But a stagecoach vanishing without a trace, now... Hired to protect the next
coach and its important passengers, Lucky Luke finds himself teaming up with a
particularly irritated Calamity Jane – something of hers was on the missing
vehicle. The two of them soon begin hearing rather unpleasant rumours:
whispers that the disappearance was caused by ... a mysterious ghost!
