Madman’s Bend : The Body at Madman’s Bend [EPUB ebook] 
The Body at Madman’s Bend

If any man was ever born to be murdered, it was William Lush – a hated drunk who disappeared after beating his wife to death. Plenty of men had the opportunity to murder Lush, some the means, none the motive. Jill Madden, his pretty step-daughter, had all three… When Lush disappears, Inspector Bonaparte must look for a body – and the murderer – before the Darling River rises to flood level…
This novel is one of Upfield’s major accomplishments… Bony’s determined search no matter where guilt falls is fascinating… This book is Upfield at his best. – from
