This is LBC from Global, leading Britain's conversation. Mystery Hour with James O'Brien.

Four minutes after 12 is the time. I'm going to solve a mystery for you in the course of this hour.

I've received a lot of communications in the last couple of

weeks about whether or not you've been blocked or somehow your messages to me are not being

reached because you no longer see the ticks on your WhatsApp message. I'm going to solve that

mystery for you today. But of course that is not the main purpose of this part of the program.

It is your weekly opportunity to achieve the sort of satisfaction, not ordinarily available, anywhere else on your radio dial.

The way it works is thusly.

You ring in with a question, a mystery, a riddle, a conundrum, and someone else will ring in with the answer.

It is actually as simple as that.

The magic happens in the margins.

It may not sound like something that allows me to guarantee a laugh-out-loud moment

or some genuine enlightenment or indeed to promise that you will know more by one o'clock than you do now.
