01 Their conversation hit me like a bullet to the chest , killing all the joy I'd felt after getting my pregnancy test results . I'd gone to our private clinic early that morning for the results . I was planning to surprise him at the dress fitting . Instead , he delivered the killing blow . " Boss , keeping this from Saoirse ... it's dangerous . " That was his right - hand man , Declan , speaking in the private room next door . " In our world , secrets like this get people killed . " " I don't have a choice . " Cillian's voice was heavy with exhaustion . " Delphine carries my brother's only child . The future heir of the O'Sullivan territory . My father made me swear a blood oath before he died . " " But marrying her ? Behind Saoirse's back ? " " Which is why she can never know . " His voice turned to steel . " The wedding ceremony continues as planned . I'll give Saoirse everything she deserves . As for Delphine , the marriage certificate is just paper . Protection for the child's inheritance rights . " I leaned against the imported marble wall , my hand instinctively moving to my stomach . So he was already married to someone else . If he had a legal wife , what did that make our wedding ? A sham ? A joke for our enemies to laugh at ? The boutique's designer approached - one of the few civilians we trusted with our business . " Miss Brennan , Mr. O'Sullivan's custom gown is ready for fitting . " Her words made the room spin . Cillian had overseen every detail of this wedding personally . In our world , most marriages were business arrangements . But he'd insisted ours would be different . He'd designed everything himself - the rings , the dress , every detail perfect . Inside my engagement ring , he'd engraved : " Till death do us part . " I'd told him to delegate it to our people . The O'Sullivan crime family didn't run itself . But he'd refused . " This shows my commitment . When you wear these things , you'll know you're mine . " Every family in Boston's underworld envied me . Who knew his love would be such a cruel betrayal ?
