"Beef blood," Adam lowers his voice to a whisper. So do the brothers.

"Not BEEF blood," Gustav whispers.

"BULL’S blood," hisses Dmitri.

"A BLACK one." Dmitri’s eyes flash.

"We boil it for two hours."

"Stirring every seven minutes."

"The food inspectors don’t like it."

"They don’t like secrets."

"We use it in almost everything," Gustav finishes triumphantly, and Adam flashes you a significant look.
