Prunus foliage shrivelled and dried up

I have a Prunus Royal Burgundy a few years old and planted last autumn. It flowered very well and seemed healthy until the recent heatwave. I watered it along with everything else, but some of the leaves are dried and shrivelled, as in the attached photo. Does anyone know what's wrong and how to treat it? Thanks very much.
