a string of (good) luck

A period of continuous good fortune. We've had a real string of luck ahead of the build. The planning permission came through very quickly, the bank approved our second loan application, and the weather is supposed to stay sunny and dry for the next few months. With this refund from the government, it looks like my string of good luck is still going strong! You won money at the casino on the same night you heard you got the promotion? Well, there's a string of good luck for you!
