Complete story — includes the ending
A double murder appears to be revenge for the deaths of children poisoned by GHB, the inadvertent result of cost-cutting measures taken by the Indian manufacturer of toy beads. Each of the victims received five orange beads in the mail. The father of one of the children confesses, but Sherlock deduces that he is lying. FBI agent Vince Boden refuses to provide whatever information the agency has, citing policy. Evidence vital to the case against the murdered men has gone missing, which complicates figuring out the motive for the crimes. At first, Sherlock suspects the prosecutor, US Attorney Angela White, as the collapse of her case would end her ambition to be elected to a Senate seat. White admits to being blackmailed by one of the murdered men, but denies killing them. Then Sherlock realises who the killer is. Boden wanted the case to never come to trial, so he could then easily steal the no-longer-needed evidence: the GHB, an addictive drug worth millions of dollars on the black market.
