Play this tape to hear ZM's $50,000 Secret Sound

The crime scene had no fingerprints, no witnesses, only a sound. 

Lead Detective Sound Keeper Brooke has a case for you to crack with a $50,000 reward thanks to our friends at NEON.

📼 Roll the tape below to HEAR the sound. 

If you think you know what it is, call 0800 DIAL ZM at 7am, 8am,12pm, 4pm & 5pm for your chance to guess the sound and win the cash. ☎️ 

All intel to date has been gathered in one place. Agents, examine the evidence and connect the dots here.

ZM's Close Friends get early access to intel. I've already sent out a newsletter with non public information about the case. Who's to say I won't do it again.
