Dead March for Penelope Blow

A timid little spinster calls several times at Scotland Yard asking for Inspector Littlejohn,who is however away working on a case. When he returns and follows up her call,he finds that she has died after falling to her death from the window of her bedroom.
Littlejohn feels a responsibility for her and decides to investigate the supposedly accidental death,which soon proves to be murder.
The investigation takes the Inspector,together with his faithful assistant,Sergeant Cromwell to the town of Nesbury and the house of the Blow family where the death took place.
Bellairs then assembles for us the suspects which include a large number of Blows .He also introduces us to several other characters,many of which are in the mould of Bellair type eccentrics. These include Dr Cross,John William Slype (the cross-eyed window-cleaner) ,the wonderfully named Rev.Ethelred Claplady and the Chief Constable Cardew.
A good Golden-age detective tale,well told. ( )
