The melody of death

In a dimly lit street of 1920s London, a modest diamond office at Little Hatton Garden prepares to lock away a fortune worth sixty thousand pounds. The owner, a genial merchant, shares a nervous chat with a plain‑clothes officer, asking for an extra watchful eye over the safe. As night deepens, the officer returns to his post, unaware that three strangers are already moving confidently through the doorway. Their presence turns a routine closing of the shop into a silent, precise intrusion.

The intruders work with an almost musical rhythm—one humming a low tune while a blow‑pipe hisses against the steel door, the other arranging delicate tools on the floor. Their calm banter about mirrors and optics hints at a professional partnership, yet their confidence borders on reckless bravado. As the flame eats through the old‑fashioned lock, tension builds for the merchant and his clerk, who remain blissfully unaware of the danger humming just above their heads.
