The new Mrs. Meredith has invited all her friends from her freer, wilder life in London to meet with her at her husband's family home in rural Sussex. However, she is seemingly taken ill and can't accompany the party on their final jaunt to a neighbor's house after dinner.
Her husband, step-sister and friends sit down for dinner just before departing when they hear a scream from Mrs. Meredith's room, shortly followed by the report of a gun. The household ascends the stairs to find the young wife murdered, shot from close range.
Set in the year 1918 at a landed families mediæval moat-house, an imposing pile which boasts a colorful past of fire, theft and ghostly apparitions, The Hand in the Dark is in many ways a conventional murder mystery of its time and place, although there are some distinguishing features.
The most significant of these is an informal three-way duel between detectives of the old and new school. The old school is represented by 'the loud officialism of Merrington', the new school by the 'more subtle deductive methods of modern criminology' used by Caldew.
Both Scotland Yard men, however, have their limitations and prejudices which lead them after false trails, and it is left to a third, superior figure, private detective Mr. Colwyn, to blend both methods and let the facts speak for themselves, however unlikely they may be.
There are more than a few stiffly ornate phrases typical of the time but generally the writing is decent enough, and the mystery itself is actually a pretty ingenious one, where novel invention and unforeseen circumstance both play a convincing part.
Also, though very much an english country house mystery, I may have imagined it but the tone seemed to suggest a hint of archness at times, which may have been due to the author's Australian rather than British origins. What do you think?:
'Tufnell's first impulse was to take to his heels, but he was saved from this ignominious act by the timely recollection that he was an Englishman, whose glorious privilege it is to be born without fear.'
He's definitely taking the piss.
