KEY WITNESS (4.5) by Christy Barritt: Elle Philips’ life is threatened by bank robbers when they learn she contacted 911 during a heist. Denton works for Elle’s father, a senator, and is hired to be her bodyguard. Elle is intrigued by Denton, but she’s wary of another bad relationship. When those close to Elle are killed, she wonders if it is related to her sister’s murder or if someone is trying to sabotage her father’s campaign. Can she trust Denton with her life, or is he misleading her? Barritt skillfully weaves two simultaneous lines of engrossing suspense in this installment of The Security Experts series.
