David Frith, who has written a book on cricketer suicides, explores the matter further in an article in Daily News and Analysis.

There are theories as to why cricket seems to have such a high rate of self-destruction (to which may be added alcoholism, which is what one might term Suicide Mark 2). It seems to me that the long days of dedication which cricket demands by its often punishing format can wear a man down, especially when he doesn’t know where his next run or wicket is coming from. Despite the comradeship on the field and in the dressing-room and club bar, a man who is out of sorts still needs somehow to find a good night’s sleep.

A vicious circle is created: sleepless night, worrying about the next match, brooding over recent failures, which can even seem like humiliations; followed by further nervous performance and an extension of the bad run of form or, perhaps worse still, bad luck, such as a bad umpiring decision against you. It is all very wearing.

Ayaz Memon writes in Livemint that Peter Roebuck's shocking death may revive the debate on whether cricketers are more prone to suicide than other sportspersons.

This is an unusual and chilling premise which seems to fly in the face of common perception. What makes a cricketer so different from a footballer or Formula One driver, one may ask. But documented evidence would suggest that the premise is not entirely unfounded, for suicides in cricket seem to outnumber those in any other sport several times over.

The Guardian's Mike Selvey writes that Roebuck distanced himself from the English media for the wrong reasons.

Michael Henderson, writing for the Spectator, says that Roebuck, who wrote a history of Somerset cricket, was following in one of the county’s macabre traditions.

Peter Roebuck funded the education and well being of several underprivileged youth in Africa. One such person lucky to cross Roebuck's path was Psychology Maziwisa, who met him in Harare during a Test match in 1999. Maziwisa recounts his experiences with Roebuck and how the friendship turned rocky when Masiwiza became associated with the Zanu-PF party. Read on in the Sydney Morning Herald.

It is no small thing to take anyone under one's wing and to proceed to nurture them with everything one has, including one's own resources. For what it's worth Peter had over 35 Zimbabweans in his capable care at the time of his death and my guess is that he had spent something in the region of $500,000 of his personal funds to help realise some African dreams. Put it this way: whatever the precise circumstances of his death he has left the world a better place.

Nearly 20 years ago, Roebuck wrote the foreword for David Frith's book By His Own Hand, which looks back at cricket's dark past with suicides. In the Independent, Frith writes that some of Roebuck's observations back then of the fragility of cricketers now seem haunting, in light of his death.

Most poignant of all now is to reflect on Roebuck's almost triumphant claim in that foreword: "Some people have predicted a gloomy end for this writer," he wrote of himself. "It will not be so."

In the Telegraph, Steve James remembers Roebuck as the man who inspired him to write about his county experiences and also to join university.

I remember what he said because I kept it written on a scrap of paper. I still have it to this day. “It is the stance of any man of dignity to try to be able to dictate to one’s employer, not let them dictate to you,” he said. “Getting a degree allows this to happen.”
