The present and the past overlap linking the loss of a jewel belonging to Mary Queen of Scots during her flight from Loch Leven with the arrival of two suspicious men. The boys foil the plot of the two men but in the process discover the real secret of Stromm - the Tower itself. A series of hair-raising and cliff-hanging adventures bring the story to a close, during which the boys learn quite a lot about themselves and their relationship. STROMM TOWER was inspired by a family holiday in Scotland and a visit to Culross where there is a fine watching tower and a panelled gallery. Mary Stuart did in fact loose a jewel during her flight from Loch Leven.
