When a promising young actress commits suicide there is a whiff of blackmail in the air and Clay Harrison, now England's most famous detective, is enlisted to investigate. The tangled web of sex, drugs and further blackmail he uncovers will reveal suspects much closer to home than he ever imagined.

But the trail eventually leads to a quiet seaside village where Clay Harrison faces a showdown with the most brutal and dangerous enemy of his career.

First published in 1935, Methylated Murder is the final Clay Harrison mystery. Although the author went to write more books, he never returned to the characters of Harrison and Henry, with which he first made his name. This ebook edition makes this crime classic available again for the first time in over 80 years.
