The titles in James R. Benn's Billy Boyle series are all great deals at Kobo Canada with the unlimited use 50READ coupon (expires today), since Soho Crime is still couponable in Canada. They are all CAD $3.50, except the first, which is $1.79, so when you use the coupon, they come out to $1.75 and $0.90 respectively (plus tax).
I've read and enjoyed the first few titles in this series from the library, but haven't picked up many for myself since Soho Crime titles tend to be a bit pricey. So, I filled in all my gaps and have some happy reading ahead!
