‘A remarkable debut.’ – AJ Finn

‘Exquisite prose, an exhilarating case and expertly crafted. A perfect follow up to a brilliant debut.’ – Sam Holland


Unsound is the next instalment in a series that just keeps getting better! Heather Critchlow’s writing is razor sharp, with not a word wasted. All the pace of a podcast, set against the backbone of a book that propels you through a history of heartache, and spits you out the other side in a way you’ll not forget in a hurry.’ – Robert Rutherford

Unsound is another stunning outing for Cal Lovett. An old mystery, past secrets and characters that jump off the page, including turns of phrase that are quite exquisite, Heather Critchlow has pulled out another cracker of a book and I cannot wait for number four which is so brilliantly teased.’ – James Delargy
