Three Boys; or The Chiefs of the Clan Mackhai, by George Manville Fenn.
________________________________________________________________________
This time the Manville Fenn formula of peril after peril does not lead
us abroad but to an almost ruined castle on the north-west coast of
Scotland.
Max is the son of a London lawyer, from whom the Clan Chieftain has been
borrowing large sums of money and not repaying them, so that in the end
the Castle is distrained upon. Meanwhile Max, who has been sent up to
the Castle to stay with the Mackhais, has been put through test after
test of his bravery by the Chieftain's son and his gillie.
With this information the end of the story is almost predictable, yet we
read of peril after peril, and still we feel sure that this one must be
the last.
