The valley is riddled with abandoned mineshafts that still contain some coal but that are so dangerous because of the possibility of methane gas explosions and roof collapses that they are actually illegal to enter. One of them is even called Dead Man’s Mine, and that’s the one that John Walter and his friend Albert get trapped in.
Mac’s got to step in and try to save his cousin, at the same time avoiding other Lethbridge perils such as the plentiful rattlesnakes and the tricky train trestle. Can he handle it all?
With breathtaking action sequences, and his trademark skill at recreating historical settings in this series, Dave Glaze has fashioned another nail-biting adventure for young Mac Davis.
