When their mother becomes unnaturally sleepy and forgetful, they become suspicious of her new boyfriend. With help-and a watchful eye-from their mysterious wheelchair-bound gran, they set out to crack the mystery. Will they succeed? They'll need a combination of fast talking, quick thinking, rule breaking, medical investigation, and determination-plus a good dash of 'that spooky twin thing'-to cure this crime. A fun fresh take on the detective genre, full of excitement, humour, and medical know-how!
