An enjoyable Chalet School tale, with the central characters, the Herbert sisters well-drawn and likeable. The other sisters of the title, the Maynard triplets, seemed remarkably precocious, but then I suppose Joey's children would be! There's the usual CS mix of feuds, Guides, Christmas plays and minor adventures, set against the backdrop of the last months of 1944, with the War intruding into the school itself with some bad-feeling against German-speaking pupils. That was well handled, with the demoralising gently done. A lovely read.
