Take all the work out of being a successful investor

That investing business can be hard work, can't it? Keeping a close eye on your portfolio can leave little time to do anything else, especially when shares and funds are being traded 24 hours a day.

But how about a strategy where you only need to take action twice a year? A new book has details of two, plus a third that only entails a monthly look at your investments. The Idle Investor by the global equity portfolio manager Edmund Shing offers "a straightforward investing method that lets you get on with your life while your money grows in the background".

The book, published by Harriman House, sells for £16.99 but 10 Bargain Hunter readers can win a free copy. To be in with a chance of winning, simply send the answer to the following question to yourmoney@independent.co.uk by next Thursday, 2 July. The question? Which Monty Python member wrote and sang the hit song Always Look on the Bright Side of Life?
