Let me know when you’re somewhere I can meet you

then sat down in her vacated chair, ready to do his fair share of answering inquiries and paying invoices.

However, he found it hard to focus after the second night on a sleeper. Five minutes later he checked his mobile but Robin had not responded, so he got up to make himself another mug of tea. As he raised the mug to his lips he caught a faint whiff of cannabis, transferred from hand to hand as he and Shanker said farewell.

Shanker came originally from Canning Town but had cousins in Whitechapel who, twenty years previously, had become involved in a feud with a rival gang. Shanker’s willingness to help out his cousins had resulted in him lying alone in the gutter at the end of Fulbourne Street, bleeding copiously from the deep gash to his mouth and cheek that disfigured him to this day. It was there that Leda Strike, returning from a late-evening excursion to purchase Rizlas, had found him.

To walk past a boy of her own son’s age while he lay bleeding in the gutter would have been impossible for Leda. The fact that the boy was clutching a bloody knife, that he was screaming imprecations and clearly in the grip of some kind of drug made no difference at all. Shanker found himself being mopped up and talked to as he had not been talked to since his own mother had died when he was eight. When he refused point blank to let the strange woman call an ambulance, for fear of what the police would do to him (Shanker had just stuck his knife through the thigh of his attacker), Leda took what, to her, was the only possible course: she helped him home to the squat and looked after him personally. After cutting up Band Aids and sticking them clumsily over the deep cut in a semblance of stitches, she cooked him a sloppy mess full of cigarette ash and told her bemused son to find a mattress where Shanker could sleep.

Leda treated Shanker from the first as though he were a long-lost nephew, and in return he had worshipped her in the way that only a broken boy clinging to the memory of a loving mother could. Once healed, he availed himself of her sincere invitation to drop round whenever he felt like it. Shanker talked to Leda as he could talk to no other human being and was perhaps the only person who could see no flaw in her. To Strike, he extended the respect he felt for his mother. The two boys, who in almost every other regard were as different as it was possible to be, were further bonded by a silent but powerful hatred of Whittaker, who had been insanely jealous of the new element in Leda’s life but wary of treating him with the disdain he showed Strike.

Strike was sure that Whittaker had recognized in Shanker the same deficit from which he himself suffered: a lack of normal boundaries. Whittaker had concluded, rightly, that his teenage stepson might well wish him dead, but that he was restrained by a desire not to distress his mother, a respect for the law and a determination not to make an irrevocable move that would forever blight his own prospects. Shanker, however, knew no such restraints and his long periods of cohabitation with the fractured family kept a precarious curb on Whittaker’s growing tendency towards violence.
