When China's Huishan Dairy discovered in March that one of its chief finance executives had left due to "work stress", it was just the start of a disturbing story of mysterious disappearances.
Just days later, the next thing to vanish was $4.1bn (£3.18bn) of the company's market value after the shares fell 91% in a single day.
Now the company has said it is missing about $357m in cash.
In a statement on Monday, Huishan said its accounts had indicated it should have $426m in cash, but its banks could only account for $69m.
Meanwhile, the company has said it had "encountered tremendous difficulties" in preparing its financial statements.
While Huishan tries to make sense of its accounts, it is pertinent for investors to be reminded of one of the – thankfully rare – risks to equity investing. The accounting scandal.
Although rare occurrences, it is also rare for equity investors to get anything back should a company go bust following such an event.
Let's look at some historical examples.
The biggest audit failure in US history, the energy trading firm's actions not only destroyed Enron, but also one of the biggest audit firms in the world – Arthur Andersen.
The saga begins during the late 1990s as Enron's unwieldy business structure is found to be hiding a network of companies designed to hide its losses.
Two of the main antagonists, Jeffrey Skilling and Kenneth Lay, are indicted following the reporting of $137m loss at the company's broadband division, then in October 2001 a further $618m loss and a $1.2bn writedown.
Arthur Anderson legal counsel tells auditors to destroy all but Enron's most basic files.
Days later, the company is told it faces an SEC probe, and by December's Chapter 11 bankruptcy filing, its stock ends its days at 26 cents. Just a year earlier, the shares had hit a record $90.56.
Several directors served custodial sentences, including Andrew Fastow, who served four years. Jeffrey Skilling received a 24-year sentence, commuted by 10 years in 2013. Kenneth Lay died of a heart attack just days before he was due to be sentenced.
This scandal gave rise to the Sarbanes-Oxley Act, designed to clean up corporate governance.
A number of shareholders won a class action settlement of $7.185bn – the largest of all time.
Following bankruptcy, the reorganised company paid its creditors $21.7bn. Shareholders lost $74bn in the four years up to its bankruptcy filing.
In 2005 WorldCom chief executive Bernie Ebbers became an overnight sensation after being sentenced to 25 years in jail for his part in one of the largest accounting frauds in history that led to $180bn in losses for shareholders.
