Uncertain Death [EPUB ebook] 

A missing wife, a husband suspected – and only the incorrigible private investigator can save them both. Classic crime from one of the greats of the Detection Club On the day that Emily Tate vanished, Inspector Marston met her husband, Stephen Tate, on the tow-path of the River Pyle. The unassuming Stephen was on the brink of a nightmare episode that was to make his unhappy marriage, his clandestine love affair and his disappointed hopes seem positively joyous by comparison. The determination of the girl he loved was the only thing that could save him from the web of circumstances in which he was enmeshed. She sent for Detective Arthur Crook.
