The Mystery of the Blinking Eye — Kathryn Kenny

"Great-headed man, with blinking eye, A shaded road, a horse's cry, Foreign words for all to hear, First clue is now so very near. Watch out for thieves; they're everywhere, At home, on island, dead beasts' lair. Where shines a beacon 'cross the sky, Beware, great danger lurks close by. Thus begins the strange prophecy that spells adventure for Trixie and the Bob-Whites."
