Un rhyfedd yw Erful, yn byw bywyd unig. Yr unig atgofion hapus sydd ganddo yw'r rhai o'i gyfnod yn yr ysgol. Felly, pan gaiff un o'i gyd-ddisgyblion ei llofruddio, teimla ei bod yn ddyletswydd arno i ddatrys y dirgelwch. Rhaid iddo ymdopi â'r byd tu allan i furiau ei gartref, ac os yw am oroesi, rhaid i Erful fynd i'r afael â'i orffennol ei hun.
Title translates as "Old small children" but refers to a nursery song in Welsh, sung to get small children to sleep, which starts "Heno, Heno, hen blant bach". "Heno" means "tonight".
Still looking for a Welsh language author I can really enjoy. Gwen Parrot writes quite well, but sadly the genre of this one was off for me. Prostitutes, murder and a whodunit... not really my thing. The saving grace of this book is Erful, the protagonist, who has Asperger's syndrome, and is a carefully created character.
Erful has Aspergers syndrome, is thus considered odd and is lonely as a consequence. His only happy memories are those of his childhood school days. When a former pupil is murdered, Erful sets out to solve the case, which is a challenging prospect for someone like him. By happy coincidence, he runs into a range of old school friends and acquaintances. In the end there is a bit of a twist.
