We are delighted to publish this classic book as part of our extensive classic literature collection. This book is a reproduction of an important historical work. Unlike some other reproductions of classic texts, We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. Also in books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy. We use state-of-the-art technology to digitally reconstruct the work, preserving the original format whilst repairing imperfections present in the aged copy. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in our edition. We do, however, repair the vast majority of imperfections successfully; any imperfections that remain are intentionally left to preserve the state of such historical works.,,The Penrose Mystery", fist published in 1936, is definitely up to the high standard of the wonderful Dr. Thorndyke series. Penrose is an eccentric old man in possession of some dazzling gems, which he won't insure. When Dr. Thorndyke is alerted to a burglary at his house, a scrap of paper is found with the word 'lobster' on it along with two Latin words. Meanwhile, Penrose has fled in panic after a car accident. The police believe he's gone into hiding to avoid a manslaughter charge after a hit-and-run accident. Finding him is a forlorn hope, there's so little to go on. But Thorndyke has a way of seeing significance in the merest bits of dirt inside a tire or oddments in a pocket... Polton, Dr. Thorndyke's lovable lab assistant, has an important presence in the plot, less this time for his remarkable technical skills than for his fondness for fixing antique clocks.
